Electric guitar...

1st I figured out what my goals are, do you want to be able to play in a band and or jam with friends ? singer songwriter? accompany yourself and or singer ? play at a campfire type thing or just learn your favorite licks riffs and solos most fall under the last but would have problem doing any of the others.

So each one would take a different approach on what you need to know and practice.

I'd would also get a drum pad and sticks and learn the basic drum rudiments with a metronome rhythm and counting helps so much this will help your playing a ton.
