Plan Your Journey

The way to ensure that you stick to a plan is to make it rewarding. If you are continually rewarded for sticking to the plan, you will stick to the plan. It's a good cycle.
I don't mean eat a cupcake every Fridayif you avoid sweets for a week. (But, hey, if that will continue to work for you - go for it).
Break up your end goal into smaller chunks. These can be as short as a week or a month. It will depend on you, and the nature of your goals.

The 531 plan is a good example: Three weeks out of four you get a chance to break a record. That kind of continual success helps one to stick to a plan that is otherwise pretty plain.

Do the same thing with your goals. Set the long-term goal that resonates with your inner desire, then break it up. Each week (month) knock down a piece of it. Pretty soon you will achieve what you desire.
