Set small, measurable, attainable, and challenging goals. Start with the end result and break it down into the short, medium, and long term goals to reach it. Post pictures of your goal everywhere and keep it as your focus. This is a calculated formula and can get you from point A to point B in a timely manner.
Alternately, you could just quit worrying about it and roll with life as it comes.
Either way - be well.
