It's always too early to quit.
Do not weep do not wax indignant. Understand.
If you can dream it, you can do it.
The dog that trots about finds a bone.
To be a good loser is to learn how to win.
Go for it now. The future is promised to no one.
Never complain and never explain.
The wise does at once what the fool does at last.
Begin to be now what you will be hereafter.
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.
