You never know what motivates you.
The secret of getting ahead is getting started.
What you do today can improve all your tomorrows.
Who seeks shall find.
Begin to be now what you will be hereafter.
Without hard work, nothing grows but weeds.
It's always too early to quit.
Expect problems and eat them for breakfast.
Always desire to learn something useful.
If you think you can do it, you can.
If you know you are on the right track, if you have this inner knowledge, then nobody can turn you off... no matter what they say.
