I have written some of them, but all of them are special to me in some way. The most precious commodity we have on this earth is time. It can never be returned or exchanged. We never know how much we have left or how little. It is each person's responsibility to decide what is important in their life and what they will spend their time on.
Time is life.
It is Irreversible and irreplaceable. To waste your time is to waste your life, but to master your time is to master your life and make the most of it. It isn't about who you've kissed, what sport you play, or which guy or girl likes you. It's not about your shoes or your hair or the color of your skin or where you live or go to school. In fact, it's not about grades, money, clothes, or colleges that accept you or not.
