Since i am not allowed to watch porn or sexually satisfy myself, i don't really know what to do in my life. I have signed up in the local gym, to gain some muscles and become more fit. I read books a lot more now, and i go to the local sauna to get a nice glowing skin that lasts for 1-2 days? Anything else that has helped you spend your time more productively?
Go to a coffee shop and talk to people. Men, women, young or old, it really doesn't matter. Not only is this great way to spend time, but it also improves your social skills, which will make it much easier to talk to girls and possibly find a girlfriend in the future.
Draw, paint, play music if you can -- learn how to play if you can't. Try some basic meditation techniques. Maybe start some sport -- jogging or hiking if you're not into competetive sports. If you are, join a team of some sort. There are lots of things you can do away from the computer and / or TV. I'm not saying those are bad but all things in moderation -- except fapping which, at this time, should not be a choice obviously. Good luck. Stay positive!
Learn anything that interest me. I'm learning sign language, guitar, ukulele, juggling. I can't do those at the beginning of the year, not even a bit. Now I CAN
Pick a musical instrument, guitar would be easiest. There are plenty of books that allow you to teach yourself or you can get lessons.
Joining social/sports groups is the best way. You feel better because of physical exercise and its benefits and you develop real friendships and relationships.
