By failing to prepare, you are preparing to fail.
Go for it now. The future is promised to no one.
Be thine own palace, or the world's thy jail.
Expect problems and eat them for breakfast.
You never know what motivates you.
The dog that trots about finds a bone.
Quality is not an act, it is a habit.
Leap, and the net will appear.
It's always too early to quit.
Always desire to learn something useful.
