Hi, I’m Lachlan, the guy behind Hack Spirit—and like you, I’ve had my fair share of “Why did I say that?” moments.

You know the ones.

Where the words are out before you can stop them, and the aftermath is an awkward cocktail of regret, overthinking, and a touch of self-reproach.

It’s human, right?

Oversharing happens to the best of us, whether it’s spilling your deepest fears to someone you barely know or unloading a little too much on a friend who wasn’t ready for it.

I’ve been there, and I’ll admit—it stings.

Over the years, I’ve turned to psychology to understand these moments, and what I’ve found is eye-opening: there are certain things we’re almost always better off keeping to ourselves.

In this article, I’m breaking down seven of those things—lessons learned the hard way and backed by a little wisdom.

1) Personal grudges

Psychology has taught me that holding onto grudges is like drinking poison and expecting the other person to get sick.

It’s a no-win situation.

We’ve all had moments of betrayal, hurt, or disappointment.

It’s natural to feel angry and upset.

But sharing these grudges with others often just fuels the fire, causing further damage.

In my studies, I found that it’s more beneficial for our mental health to work on forgiveness instead.

This doesn’t mean you have to forget what happened or allow toxic people back into your life.

What it does mean is choosing to let go of the anger and resentment for your own peace of mind.

When you start to feel the old grudge bubbling up, try to shift your focus onto something positive.

Practice deep breathing, go for a walk, or write in a journal.

You’re not doing this for them – you’re doing it for you.

This is one of those things that’s best kept to yourself, for the sake of your own mental health and wellbeing.

2) Your biggest fears

Sharing fears can sometimes help to lessen their power, but there are instances when it’s better to keep them to ourselves.

I learned this the hard way.

A few years back, I shared my fear of failure with a colleague, hoping to find some comfort and understanding.

Instead, my fear was used against me in a competitive work environment.

It was a tough lesson, but it taught me that not everyone has your best interests at heart.

This aligns with research indicating that in competitive settings, individuals may be reluctant to share personal concerns due to fear of exploitation.

As the famous psychologist Carl Jung once said, “What you resist, persists”.

Instead of giving voice to my fears and inadvertently feeding them, I learned to face them head-on.

Rather than telling others about your fears, confront them yourself.

Use them as a catalyst for change and personal growth.

3) Personal achievements

We all love to celebrate our successes, and there’s nothing wrong with that.

But sometimes, constantly talking about your achievements can come off as bragging or insincere.

I remember when I first started Hack Spirit, I was so proud of what I had accomplished that I wanted to share it with everyone.

But I quickly realized that not everyone appreciated my enthusiasm.

Some people seemed turned off by my constant talk about the blog’s success, and I could sense a growing distance in those relationships.

That’s when I learned to be more mindful about sharing my achievements.

It’s not about hiding your success, but rather about recognizing the right time and place to share it.

Instead of constantly talking about your achievements, try to focus on what you can learn and how you can grow.

Celebrate your successes, but don’t let them define you.

After all, personal growth is a journey, not a destination.

4) Personal finances

Money can be a touchy subject, and for good reason.

Discussing personal finances, especially the details about income, debts, or savings, can lead to comparison, judgment, or even resentment.

I’ve noticed this in my own life.

Once, during a casual conversation with friends, I mentioned my recent investment in a start-up.

Instead of the positive reaction I expected, I was met with awkward silence and a noticeable shift in the mood.

A study conducted by the National Bureau of Economic Research supports this observation.

The study found that when people are given information about their peers’ incomes, it can lead to unhappiness and demotivation, especially if they perceive themselves as earning less.

So it’s better to keep the specifics of your financial situation to yourself.

If financial advice is needed or sought, it’s always best to consult with a professional.

It’s not about hiding your wealth or lack thereof; it’s about maintaining your peace and the quality of your relationships.

5) Relationship conflicts

Every relationship has its ups and downs.

But airing out your relationship conflicts in public, or even among friends, can lead to more harm than good.

I recall a time when I was going through a rough patch with a close friend.

Out of frustration, I shared our issues with another mutual friend.

Word got around, and it only added fuel to the fire.

What I thought would help diffuse the situation only made things worse.

It taught me that involving others in your relationship problems can often complicate things further.

Instead, try to communicate directly with the person involved.

It might be difficult at first, but it’s the most respectful and effective way to resolve conflicts.

Your relationships are personal and private.

Keeping them that way can prevent unnecessary drama and maintain the integrity of your connections.

6) Negative opinions about others

We all form opinions about people around us.

That’s human nature.

However, voicing negative opinions about others can create a toxic environment.

I remember a time when I was caught up in office gossip.

I found myself casually sharing negative opinions about a colleague.

It seemed harmless at first – just small talk.

But over time, I realized it was affecting my perspective and interactions with this person.

As the renowned psychologist Dr. Wayne Dyer said, “Judgments prevent us from seeing the good that lies beyond appearances.”

Sharing negative opinions not only affects our relationships with others but also reflects poorly on us.

Sharing negative opinions about others can create a toxic environment, as supported by research indicating that negative workplace gossip significantly reduces employees’ organizational self-esteem and positive workplace behaviors.

Instead of voicing negative opinions, try to focus on the positive aspects of a person.

And if you do have a problem with someone, it’s best to address it directly with them in a respectful manner.

7) Your good deeds

It might seem counterintuitive, but sharing your good deeds can sometimes diminish their value.

When you do something kind or generous, the act itself should be its own reward.

Broadcasting it can often make it seem like you’re seeking validation or praise.

I experienced this firsthand when I started volunteering at a local shelter.

Initially, I would share about my experiences on social media.

But over time, I noticed that the focus was shifting from the act of giving to the praise I received for it.

The renowned psychologist Albert Bandura once said, “The standards we set for ourselves guide our moral course.”

Doing good should be about contributing positively to the world, not about seeking recognition.

Conclusion

In our world of constant sharing, it can be beneficial to keep some things to ourselves.

Not only does it maintain our personal boundaries, but it also promotes healthier relationships and a more positive self-image.

But the goal isn’t to bottle up your feelings or experiences.

It’s about discerning what to share and what to keep private for the sake of your own well-being and that of others.

So next time you feel the urge to share, take a moment to reflect: Is it necessary?

Will it contribute positively?

If not, perhaps it’s one of those things better left unsaid.

After all, as the saying goes, “The wisest man is the silent one. Examine his actions. Judge him by them.”
