Smart goal setting is something I've done consistently for years. My problem is supplying the action required to take the goals from my notebook to my reality.
Smart is actually an acronym for a goal setting formula. When writing down your goals, you should make them specific, measurable, attainable, realistic, and time-specific.
This formula works for a number of reasons, but most times I notice that I lack the sticktuitiveness to accomplish anything. I completely lack focus and it really makes me... oh, wait, I think I just thought of another goal!
