"Don't sacrifice what you want most for what you want now. Write down what you want most and see if often." 

Peter Vidmar 

 What this means is that set your priorities and follow through with them, and I agree. When you trail off from your dreams of getting high grades, you'll fall flat and fail. If you stray away from trying to lose weight and quit exercising you'll find yourself back at the beginning, and you'll regret taking the break. However, if you focus on your goals you'll most likely achieve them and you'll be proud of yourself. Remember to focus on your goals, but also set aside some time for yourself and friends and family.
