I was happy to read that you're at such a wonderful point in your life and also felt nostalgic for those days. Young, healthy and with the right kind of knowledge at hand. You seem like a smart guy and there's probably no need to warn you about mistakes I've made but still. Do not waste time on unworthy ventures or compromise your health. Make money, get more skilled with all the things your body can do and maybe if you haven't already, learn how to play an instrument, another language or two... All that while having fun along the way. Also what made my life richer and more meaningful were all the places I've traveled to and people I've met there. Visited a lot of ancient temples and countries where life is quite different from my homeland and that gave me a different perspective on things. Last but not least, if you're persistent with meditation and keep growing you'll become much more than you even thought was possible. Hope that some of this helps and wish you success in all your endeavors.
