Make "YOU" the priority for the week. Before you make any commitments schedule "YOU" time - whether its exercise, meditation or journaling - give yourself the time to do the things you need to be successful for your goal. Then fit in the other stuff as best as you can.
You are your own best advocate! Give yourself the luxury of for once putting yourself first. After all the new, improved "YOU" will be energetic and ready to tackle everybody else's needs.
