This post is mainly targeted at all the people here who still are working on their confidence and "outcome independence", or "inner game" as some might call it, but I encourage everyone to try it out.

Set yourself a challenge for every day you live. This could be anything, as long it requires to do something you're not quite comfortable with. For example, every morning I stand sleepily in the shower, tell myself "fuck it, let's do this", count to three and let the ice-cold water pour over me. It's awful, but afterwards I feel great because I did it. Now you might ask yourself how this is related to gaming - it's that "fuck it, let's do this"-attitude which becomes a part of your daily routine. The next time you see a hot girl you tell yourself exactly that and approach her. You may believe me, even the worst rejection will not be as bad as ice-cold water being poured all over you

This is just an example of a daily challenge (though it works great). There a plenty of possibilities, eG. if you're rather shy you might think about something like talking to at least one complete stranger every day. Be creative. Set yourself a challenge every day and rock it. You are great.
