Did you realize that we have only 168 hours every week to get everything done? Will you be able to fit into your week everything that must be accomplished? Total the hours you have committed:
Divide your free hours per week by seven (the number of days per week), and you will discover how many hours per day, on average, you have for yourself, free of all obligations!
If your obligated hours total more than 168 hours per week, then your current schedule is not going to work, is it?
