You can live your entire life regretting whatever you want. Nobody will stop you. Grow a pair. Start where you stand. Do what you can with what you have. You are unique and your resources are valuable.
What the hell. don't fret over the past. It's a new day.
You can't help people who don't want to be helped.
Get on with it buddy. Don't spend one minute worrying about the past. It's gone. Life is short.
Play hard.
Best,
