Set measures to evaluate your success.

Determine a single measure to evaluate your progress
Think about your goal and the ways in which you can measure your progress in that particular area. Pick one measure.

Break your major tasks into smaller ones
Make sure that you can measure your progress even with the smaller tasks so that you can stay on track.

Work towards one specific part of the larger goal at any time
Be consistent. Accomplish at least one part of the goal and you will be closer to accomplishing the actual goal.
