Begin to be now what you will be hereafter.
Expect problems and eat them for breakfast.
It's always too early to quit.
Be kind whenever possible. It is always possible.
If you've got a talent, protect it.
Never complain and never explain.
If you're going through hell, keep going.
If you think you can do it, you can.
Go for it now. The future is promised to no one.
What you do today can improve all your tomorrows.
It sounds cliche, but success is your friends, your family, what you do, and if you're happy when you wake up.
