I found TRP late, only at 27 years old. I have been doing what is advocated here.
But I can't help but think that I am past my prime to pick up something and be good at it.
I am turning 29 in the new year, and I am just wondering what I can a man be really good at in his 30s and beyond.

I guess sports is definitely out of the question. Should I still be pursuing and taking up martial arts? (eg. BJJ, Judo)

What else? Thoughts?
