Begin to be now what you will be hereafter.
If you think you can do it, you can.
Without hard work, nothing grows but weeds.
Quality is not an act, it is a habit.
By failing to prepare, you are preparing to fail.
If you've got a talent, protect it.
Know or listen to those who know.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
You never know what motivates you.
Nobody expects to trust his body overmuch after the age of fifty.
I never expect to see a perfect work from an imperfect man.
