find the trouble spot(s)! for your experience level, even a simple thing like this can be daunting to play correctly. first of all, i know it's hard but forget about trying to learn licks without knowing where the come from. studying chord/key relationships along with practicing is important to really understand WHY you're playing that and WHY it sounds good to you.

practicing right/left hand exercises is important for any guitarist, and there's never too early a time to start adopting these things. work on picking speed with a metronome, doing quarter, eighth, and sixteenth notes at various tempos, then start working in triplets soon after. practice purely alternate picking along with only downstrokes and only upstrokes. with your fretting hand, work on various four-note-per-string patterns that are symmetrical up the neck. start to mix things up by using three-note-per-string, then two-note-per-string. always practice these exercises with alt picking.

this is simple, but the backbone for building chops. with a few months of dilligent practice, your issues will dissolve, at least the simpler ones. but by in large, ISOLATE DIFFICULTY. if you have trouble with something, find out why and find exercises to fix the problem. often, playing part of the lick over and over again, without the rest of it, can clue you in to exactly what issues you're dealing with.
