If you think you can do it, you can.
Problems are not stop signs, they are guidelines.
Without hard work, nothing grows but weeds.
What you do today can improve all your tomorrows.
Who seeks shall find.
Always desire to learn something useful.
Only the educated are free.
By failing to prepare, you are preparing to fail.
Wherever you are - be all there.
Begin to be now what you will be hereafter.

If you think education is expensive, try ignorance.
