I totally agree with what Maggior said about making sure it's usable in your playing before you move on. I know when I first started studying theory I had this idea that I could just learn all of the scales and THEN suddenly be able to write music and improvise, and I would do scales for hours a day and wonder why I wasn't getting better; theory and technique are useless if you don't know how and when to use them. Things started making sense a lot faster when I would learn or write songs using the technique... I still use scales, but I put them in different patterns and rhythms in my warmups instead of just mindlessly plowing through them.
