Im not sure if this is considered as confidence or not but I believe this is something we all need to do. Tonight some AFC took off with my little brothers gf for 1 hour, my little brother got upset and went emo to his room. I didnt end up punching the guy out(which I should have done) but I spoke up for what I believe in (guys taking off with other peoples gf at night drunk). All my life Ive listened and spoke for other people and other people have done the same for me, now Ive realised we all need to speak about whats right and what we believe in. By speaking up for yourself you will gain an incredible amount of confidence(It worked for me, hopefully for you too). Dont be scared people this is inner game stuff, after a while youll pick up your left nuts subconsciously
