The Hidden Cost of Holding a Grudge (And How Forgiveness Sets You Free)

What if the resentment you are holding right now, whether it surfaced yesterday or years ago, is poisoning your psychology?

Wayne Dyer taught that one essential quality of a self-actualized person is the inability to be easily offended. When we hold a grudge, what we’re truly doing is staying offended, and finding ways to justify it.

We organize our worldview around the wound that led to this grudge. And like the person driving around with a “Don’t Tread on Me” bumper sticker, with this filter, we scan the world for threats rather than opportunities.

The Buddha said it plainly: holding a grudge is like drinking poison and expecting the other person to get sick.

Many years ago, I read Colin Tipping’s book, Radical Forgiveness. What struck me was not just his framework for letting go, but his understanding of how perspective shapes reality.

Tipping invites us to see that things happen at a deeper level than we see at first glance. There is connection and purpose woven through our lives, even in the painful moments.

This is not the notion that everything happens for a reason. It is something far more powerful. It’s the understanding that when we shift how we look at what happened, we shift how it lands in our being.

I had carried real pain from a past relationship. When I applied Tipping’s lens— looking not just at forgiveness but at the blessing and the deeper purpose in that dissolution—everything changed.

The end of the relationship was not a failure. It was a necessity. At that moment, my life required it.

When I genuinely saw that, a weight was lifted from my shoulders. My whole orientation shifted, no longer dictated by the grudge I’d been holding. I became more trusting, more open, and more willing to receive.

I moved from a scarcity lens to an abundance lens. The world didn’t change, but my perspective did. 

That is what unforgiveness actually costs us. It does not punish the other person, but it does hurt us. It keeps us small, guarded, and stuck in time.

Forgiveness is not weakness. It is not excusing what happened. It is choosing to reclaim your own energy and your own clarity.

This is why forgiveness has become part of my daily Positive Psychology Stack.

Alongside gratitude and compassion, it is one of the core practices I return to every single day. The reason is simple.

Resentment is easy to miss. It accumulates quickly and quietly, with a small irritation here, or a lingering frustration there. If you do not tend to it consistently, it will build into a filter that distorts how you see the world and the people in it.

The daily practice is straightforward: 

Scan for any place you are holding hard feelings toward someone, including yourself. Look for the deeper purpose. Look for the blessing. Look for how the given moment is shaping who you are becoming. Then, release the charge. It gets easier the more you do it, and catching it early means it never gets the chance to take root.

When your lens is clean, you see a safer, more abundant world. You see a world where collaboration and co-creation are possible.

So here is the question for you: Where are you holding resentment right now?

And what blessing might be hidden there, waiting for you to look?
