Focus on your original reasons and see if they still apply to what is going on in your life currently.
Change or reestablish new goals if need be, set them realistically, and once reached take a moment to do something special for yourself.
Set another goal, and continue until larger goals have been reached from the completion of the many smaller goals.
In the end you may be surprised at how many goals you have reached. Developing a new goal and adding new goals to your daily life is a great way to get things done.
Stay focused, you will get there, just take it one step at a time.
