When discussing regrets, I’ve never heard anyone say that they regret taking a certain action.
People regret the areas in which they didn’t take action; we regret the things we didn’t do…even if it’s disguised as something else.
For example, I can say I regret going to college; but what I really regret is not spending that time and those tens of thousands of dollars on other things (e.g. travel, investing in myself, making mistakes which won’t put me in decades of debt, building skills, etc).
When you think about the regret you’ll feel by doing something, ask yourself: how will I feel if I don’t do this?
