or you can just put down your bass and do something else for a while...listen to music, read a book, mow the lawn...i know many of you are thinking "blasphemy! i can't put my bass down for one minute because i am 100% bass player, and music is my life!!"
well, just try it...just for at least a few hours or a day or something...nothing more than a day. when you come back, you might have some more inspiration or drive to play.
but then again, everybody needs something different. i find that if i can't come up with any good music at the moment, i'll play 18 holes of tiger woods golf 2005 or maybe go to the driving range and hit a bucket of balls...something to take my mind off music for a while...then when i come back, i will play something that i may have never thought of before, because i was forcing myself to play...but like i said, this may not work for everyone!
