How to practice
Do it on a regular basis, preferably every day from 30 minutes to 6 hours (!).
Find a certain time of the day where you can concentrate and not get disturbed by the outside world – i get up early in the morning (when my work schedual permit) and do 1 to 4 hours practicing.
Start with the “boring” stuff (i kinda like it though), playing scales , arpeggios, chords.
Go here for specific scale practice advice
I usually set my alarm clock to 10 minute intervals – then i play a certain exercise for that time period before moving on to something different, makes it easier for me when i have to “obey” the alarm
Always practice with a rhythm device – metronome, rhythm machine, software drum machine ( free soft drummachine Hammerhead ).
NEW! Ive recorded some drum patterns from my drum machine, go listen HERE
Play everything slow at first, dont speed up until you can play your lines with fluidity and in perfect time.
Keep track of your progress – keep a ledger with your practice routines/goals and maybe write in tempos.
Get some accompagment software or gadget to practice to – nice alternative to simple rhythm or metronome beat and you get chords and harmony to play to
Music minus one (bass) recordings – same examples below:
Eartraining – which is what you should practice every day.

If you get tired of hitting the pause button again and again, there’s more practical solutions
Record yourself
Inspiration
Learn to read music
A little goes a long way, go to the library and borrow everything written for the bass clave ; doublebass, cello, trombone, tuba… There’s a lot of easy classical pieces that is fun to play, and if you have a bassplaying friend you can read together and play duets, its very effective (and fun) when you’re two, you know right away when you (or your friend) make a mistake.Play with as many bands you can get into, always play with people at the same level or better than you.
Dont say no to a gig or experience.
Be willing to play for free (until you’re so good they’ll have to pay you).
Join the bassplayer forum talkbass.com, you can find a lot of answers to technique, exercises, theory….
Practice the Homer Simpson way
Practicing technical “no brain” related exercises while watching TV are possible – I frequently just lie on my sofa watching a movie while practicing various right hand finger plucking methods, just getting into the “automatic” mode – ie thumb, index, middle, ring – thumb, index, middle, ring, again and again for hours and hours (or a movie’s length)
HAVE FUN!
