Importance of Time Management

There are 168 hours in one week. I practice about twenty hours a week. A meet usually take about five hours. On average I take 17 credits a semester, which means 17 hours of lecture per week. You should sleep on average 8 hours a night, so 56 hours a week.

Those three things already take up 98 hours a week, which doesn't include studying or eating. How will you manage the remaining 70 hours (ten hours per day)?
