I agree with what Joash is saying, learn the scale then the basic chords and progressions.
lol, i was also stuck on C until I saw some of Jamal Hartwell's videos then i got hooked on Eb and I learned more in Eb than I did in C, then I transposed the chords/prgressions and runs that I learned in Eb to Db then I got hook on Db, then I learned more chords/prgressions in Db than I did in Eb....And I just kept building up like that.
LGM has so much to offer, Drastic improvement is inevitable on this site, just "seek and ye shall find"

Peace!!
