The dog that trots about finds a bone.
It's always too early to quit.
Go for it now. The future is promised to no one.
If you think you can do it, you can.
Never complain and never explain.
Wherever you are - be all there.
Only the educated are free.
The wise does at once what the fool does at last.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
Don't take too much comfort in the fact that you're successful today because tomorrow could bring failure. There's no surety in life.
