Without hard work, nothing grows but weeds.
If you think you can do it, you can.
Expect problems and eat them for breakfast.
Wherever you are - be all there.
It's always too early to quit.
By failing to prepare, you are preparing to fail.
Who seeks shall find.
The dog that trots about finds a bone.
Always desire to learn something useful.
