Similar to the other top-level reply, without perfect foreknowledge, there is no way to know you're "getting it right this time." I dated the person into me and studied what I loved. We got divorced and I ultimately ended up with a person I didn't meet until I was 30. I had to go back to school and change careers later in life because the job prospects sucked for what I loved.

Given I ultimately ended up in a good place anyway, I don't even regret anything. The only thing you can't come back from is death. As long as none of your bad decisions kill you, I don't see much to fret about.
