It's easy to look back and think: “I should have known.”

Today, you know how the relationship ended.
You know what happened with the job.
You know which warning signs mattered.
You understand things about yourself you may not have understood then.

And hindsight can make all of that feel like it should have been obvious from the beginning.

Sometimes we take what we learned because of an experience and use it to judge ourselves for not knowing it before the experience.

That doesn't mean every decision you made was a good one.
It means there's a more accurate question than:
“Why didn't I know better?”

Ask: What did I actually know then?

There's a difference between learning from your past and expecting your past self to have today's understanding.
