I use the Hal Leonard Bass Method complete edition and I practice at least 1hr. a day usually in the beginning of the day to make sure I do it. I usually complete about a page a day because I use my drum machine as a metronome. I do each exercise about 5 times 60,80,100,120,140 BPM. I do not progress to the next BPM until I get the exercise done correctly. Yes there is lots of frustration especially when you mess up right towards the end, but hey practicing an instrument is like a relationship you have to keep on working on it and don't give up. After I finish an exercise for the day I go to the Bass Guitar cheat sheet for dummies and I study the chords, scales, etc. Then I read my Music Theory for Dummies book (Just to refresh my knowledge), then I go about and read some of my Songwriting for Dummies book. After that I check out my bass hand exercise handbook and do a few exercises in that. As you can see I read a lot of dummies books but hey I really like how they break down everything, plus it's not really how we get there because we're all going to same destination. Each thing is usually considered due to how much time in the day I have, but I definitely get the exercise and cheat sheet everyday.
I've only been playing constantly for about a 2 weeks. I started officially in December and so far I've progressed pretty nicely.
My sole inspiration in bass is to be like Thomas Bangalter
