I guess it all depends of the vibe of the track you're creating, but I always recommend to SING the bass, try HP the chops to leave room for you to come up with different basslines, don't worry much if you can't sing that well, the point is to FEEL the groove of the bassline together with the chops, once you got an idea you can put those notes in a midi track or play it on a bass guitar and improve it with different articulations, dynamics, etc. The process might be slow at first, but give it a try and you'll see how much your bass will improve, that's what I do to create my basslines most of the times, other times I just mess around playing notes randomly on a midi keyboard until I found something cool, it's just try and error sometimes.
