Wisdom (?)

Finally, with my (almost) 40-year-old wisdom (?), I can now look back at all the mistakes I've made and say that should I encounter the 20 something me right now, I will tell her, "Don't even bother with this, this, and that, they will never happen." On the other hand, knowing myself as well as I do, the 20 something me would probably go ahead and make those mistakes anyway. If the not-yet 40 something myself won't listen to the 60 something myself telling me to not do X, Y, and Z. The 20 something me is definitely not going to listen to the 40 something me about not doing A, B, and C. In my own defense, however weak the defense is, our mistakes make us who we are today, right? :D
