I remember reading one time here on the forums that a good time to practice scales is while watching TV. I know most people have insanely busy schedules but one thing you have to do is give "yourself" a little time even if it is only 15 minutes.
I have made a practice schedule to keep myself focused on short term goals. This has helped me big time. Especially with chord changes. I think there is a write up about practicing in the FAQ section.
I found it. Here is the link.
