Find a local teacher that you enjoy.
It's hard to motivate yourself as you won't be able to judge your progress.
I pretty much agree, though I've run into students who were strictly empiricists about learning. With a few I told them they were wasting their money with me and should work on it in their own time whenever they felt like sparing it. Self motivation is the biggest piece of the puzzle indeed, teacher or no teacher.
And to Swensonator: I'm no guitarist, but scales shouldn't be so daunting to you. It ends up working out like this: You only really have to physically learn 12 seven-note sequences to get all the natural majors, minors, the 6 enharmonic keys, plus all the modes. C major and A natural minor use the same notes, just starting from C and A, respectively (A minor is in fact the aeolian mode of C). There are 6 "enharmonic keys" that can be thought of in terms of sharps or flats with 6 others (3 major, 3 minor), but are the same exact actual notes you're playing. It's a brain thing. B major (5 sharps) and Cb major (7 flats) are all the same notes, but are distinctly different keys, so your way of thinking of them is different. B major's major 3rd is D#, but Cb major's major 3rd is Eb, for instance.
Anyway, for your ease, here are all the natural major and minor scales and their relatives, grouped with their 12-note twins and enharmonics according to clockwise rotation through the circle of fifths:
C major: C, D, E, F, G, A, B, C
A minor: A, B, C, D, E, F, G, A
G major: G, A, B, C, D, E, F#, G
E minor: E, F#, G, A, B, C, D, E
D major: D, E, F#, G, A, B, C#, D
B minor: B, C#, D, E, F#, G, A, B
A major: A, B, C#, D, E, F#, G#, A
F# minor: F#, G#, A, B, C#, D, E, F#
E major: E, F#, G#, A, B, C#, D#, E
C# minor: C#, D#, E, F#, G#, A, B, C#
B major: B, C#, D#, E, F#, G#, A#, B
G# minor: G#, A#, B, C#, D#, E, F#, G#
(Enharmonic equivalents of above)
Cb major: Cb, Db, Eb, Fb, Gb, Ab, Bb, Cb
Ab minor: Ab, Bb, Cb, Db, Eb, Fb, Gb, Ab
F# major: F#, G#, A#, B, C#, D#, E#, F#
D# minor: D#, E#, F#, G#, A#, B, C#, D#
(Enharmonic equivalents of above)
Gb major: Gb, Ab, Bb, Cb, Db, Eb, F, Gb
Eb minor: Eb, F, Gb, Ab, Bb, Cb, Db, Eb
C# major: C#, D#, E#, F#, G#, A#, B#, C#
A# minor: A#, B#, C#, D#, E#, F#, G#, A#
(Enharmonic equivalents of above)
Db major: Db, Eb, F, Gb, Ab, Bb, C, Db
Bb minor: Bb, C, Db, Eb, F, Gb, Ab, Bb
Ab major: Ab, Bb, C, Db, Eb, F, G, Ab
F minor: F, G, Ab, Bb, C, Db, Eb, F
Eb major: Eb, F, G, Ab, Bb, C, D, Eb
C minor: C, D, Eb, F, G, Ab, Bb, C
Bb major: Bb, C, D, Eb, F, G, A, Bb
G minor: G, A, Bb, C, D, Eb, F, G
F major: F, G, A, Bb, C, D, E, F
D minor: D, E, F, A, Bb, C, D
In your spare time, work on it, and work on understanding which keys have sharps and which have flats and how many and where.
