I realize this is a broad question, but my life has changed drastically in the last few months, and I'm looking to experience more before I get too old. I know the usual answers like getting married, having kids, and so on.
I'm more interested in skills, hobbies, fields of education, practices, habits, and experiences that have shaped (for the better) the person you are today.
After the Tsunami, I told a girl I had just met that I would go there and help them in some way. She gave me a blowjob, so I felt compelled to at least try. I ended up living in Indonesia for 4 years and working my way into a global disaster response team, working in lots of countries. Almost everything I've done since then seems a bit shallow, although I recently moved to Africa, which is also extremely rewarding in another way.
