I'd say I found the perfect way for me to build up some self-esteem. I started playin my guitar constantly. i had played rarely on and off over the past months, but i'm gonna start playin constantly. i feel great playin it and i'm thinkin about how great the tunes sound that i'm playin rather than what i hate and despise.
music is excellent therapy. It is something internal. Many people think self esteem can be built by external influences, which is no true in my book.
^I love your sig! Thats cool you've found something to build your self-esteem! I feel so happy when I play my guitar and sing! Its my favorite thing to do! I agree with Bikshu that it can be therapeutic, it takes your mind off of everything stressful and lets you be creative I Love Music!!!!
