Hope for the best,prepare for the worst.
Great hope makes great man.
A rolling stone gathers no moss.
When in Rome, do as the Romans do.
Knowledge is a measure, but practise is the key to it.
Lost time is never found again.
Difficulties strengthen the mind, as labour does the body.
Behind bad luck comes good luck.
All for one, one for all.
Treat other people as you hope they will treat you.
Suspicion is the poison of friendship.
