Haha, friendly competition is good. Very very good. Competition is what drove me to be what I am, I didn't want to be like all the other bassists in the area, because their bands didn't really include them in songs. It's like, the drummer and guitarists got together and wrote a song, and played it with the bassist and the bassist made up his part right there to go with theirs. I like bass to lead sometimes, but I also like counter-melodying with guitars.
Just keep up the practice. But just to give you an idea of what I put in, around 2-3 hours weekdays, 5-6 hours weekends.
