Learn the basics.

Chords are the best place to start. They will give you strengh in your hands. Learn to play with a metronome at first. Being able to play in tempo is a necessary asset.

Alos practice your ear. Listen to songs, isolate a note and try to find it on your fretboard. Or just hum a note and try to find it.

Scales can be useful but I don't recommend them if you're just starting out. Learn the chords first.

Learning songs is a must to give you motivation. Try to get the tabs for a song you really like. See the links section you should find some good tabs sites there.
