Practice
The only way i can get myself to practice playin an instrument (guitar, piano, alto sax, bari sax) is if i pretend i was doing it in front of people. If i do not then i immediately get bored and can not consentrate, however if i sit down and practice, imagining that i am infront of people, and happen to make a mistake i feel very embarrased. i get so embarrased and frustrated that i have to stop. i imagine myself in front of an audience it so i can see the reactions of people i know, however is getting embarresed and having to stop practicing because i made a mistake and am embarred of my imaginastion a bit....out there?
Stop putting yourself down, you obvoisly sound like you know how to play
