So here's the thing.... you be you. Go make yourself happy. Do the things that make you happy.
I love this advice. I've been me more the last couple years than I was the previous 30+ years. It's great. I actually think I'm happy. I'm still single, and I think I'd rather not be, but that feels more comparable to "my marathon time was 4:28:14 when my goal was 4:20:00" and not "I can't run 5 km."
