Multi-task goal-completion work with everyday, "have to" activities
If you need to lose weight, don't take the dogs for a leisurely stroll - jog or power-walk them. Use the time you spend waiting at various appointments for catching up on trade reading or creating the materials/writing the outline for your next stunning teleclass or seminar. Take the opportunity to practice your character drawing or writing during your subway commute. If you need to do a job that is relatively mindless (weeding, ironing, dishes), use that time to listen to training MP3s/CDs or other goal-related recordings. The possibilities for implementing this tip are only limited by your imagination and lifestyle.
Always having something on hand to do that brings you closer to your goals during such "downtimes" not only frees up hours of otherwise lost time for your personal pursuits, but having something interesting and self-improving to do makes your chore time go by quicker, too.
