It's always too early to quit.

To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

Without hard work, nothing grows but weeds.

Always desire to learn something useful.

To be a good loser is to learn how to win.

Quality is not an act, it is a habit.

You never know what motivates you.

Go for it now. The future is promised to no one.
