Need advice!

Hey, so ive had a electric bass for a little while now and want to know how I should go about teaching myself how to play, you know without lessons? Not that I dont want to take lessons... I just cant afford em atm and want to learn how to play really bad. After watching some YouTube videos I just keep hitting a wall, even after practicing for awhile im just looking for a little advice! Btw some of you guys rock that bass like its nothing, it's inspiring as hell so keep rocking out and any advice will be appreciated!
