A clear vision -laser beam focus, and a winning attitude is of upmost importance to working your plan.  If you are going on a trip without a road map how will you know when you get there.  If using a GPS system and not putting in your ending point you will never get there.

Set priorities where you have several  goals , and give each a priority.  Have a large goal ,but have many small goals that are achievable to guide you along the way.  If you do not reach your goal it does not mean that you are a failure, it just means you did not reach your goal.  Just reset the goal and go for it again with very defined action plans.
