Time is something from which we can' t escape.  Even if we ignore it,  it's still going by, ticking away, second by second, minute by minute, hour by hour.  the main issue in using your time well is "Who's in charge?" We can allow time to slip by    let it be our enemy. Or we can take control of it and make it      ally(同盟) .
By taking control of     you spend your time, you'll increase your chances of becoming     more successful student. Perhaps more importantly, the better you are at managing the time you devote    your studies, the more time you'II have to spend on your outside interests .
The aim of time management is   to schedule every moment so we become slaves of a timetable    governs every waking moment of the day. Instead, the aim is to make informed choices as to how we use our time.
