I think you should set a time and place (some place quite with no interruptions, don't try playing while watching TV or talking on the phone) to practice everyday. Of course, at times you will have to rearrange your schedule. You should practice at least 15 mins. a day. You will most likely do more, but don't do less.
Your routine should cover warm up exercises (exercises with hammer ons, pull offs, bending and so on, don't forget that pinky!), chords (add a new chord as you progress, don't forget bar chords), playing by ear (just pick out songs, start simple), learn some songs (again start simple), and start slow. I realize somethings don't sound right played slow, but you need to start slow and play each chord or note perfectly. Then you can work on speed.
After all of that, you need to study a little theory. Just a little at a time or you will go nuts! At least that's what I think happened to me. I'm not called Looney Tunes for nothing!
