At that age I decided to quit my tech job and live in China for an intensive language program. That opened my eyes to so many other things.

I'm currently working on learning Korean. Also working on my private pilot license. And then there is my constant work towards a sub 3 hour marathon (I'm almost there). Dabbling with music production too.

My 20s were mostly boring, but my 30s are awesome - adventurously and intellectually so. (I'm 36)

Sure, I'll never be world class at anything, but I will constantly challenge myself. That is enough for me.
