You never know what motivates you.
Begin to be now what you will be hereafter.
Be thine own palace, or the world's thy jail.
Always desire to learn something useful.
Know or listen to those who know.
Expect problems and eat them for breakfast.
Who seeks shall find.
Be kind whenever possible. It is always possible.
By failing to prepare, you are preparing to fail.
It's always too early to quit.
I've had moments where I realize my body isn't going to withstand many more seasons, but I am very satisfied with my career and I am trying not to look at retirement as a sad thing.
