To know oneself, one should assert oneself.
It's always too early to quit.
If you think you can do it, you can.
Problems are not stop signs, they are guidelines.
Expect problems and eat them for breakfast.
What you do today can improve all your tomorrows.
Know or listen to those who know.
Go for it now. The future is promised to no one.
Never complain and never explain.
Begin to be now what you will be hereafter.
Work hard, use your common sense and don't be afraid to trust your instincts.
