Begin to be now what you will be hereafter.
Well done is better than well said.
To know oneself, one should assert oneself.
Expect problems and eat them for breakfast.
You never know what motivates you.
To be a good loser is to learn how to win.
The dog that trots about finds a bone.
Go for it now. The future is promised to no one.
If you think you can do it, you can.
Leap, and the net will appear.
Don't be afraid to fail. Don't waste energy trying to cover up failure. Learn from your failures and go on to the next challenge. It's OK to fail. If you're not failing, you're not growing.
