Never complain and never explain.
What you do today can improve all your tomorrows.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
By failing to prepare, you are preparing to fail.
If you think you can do it, you can.
Know or listen to those who know.
Things do not happen. Things are made to happen.
Quality is not an act, it is a habit.
Go for it now. The future is promised to no one.
Don't take too much comfort in the fact that you're successful today because tomorrow could bring failure. There's no surety in life.
