If at first you don't succeed, try, try again. If it ain't broke, don't fix it. If you don't laugh, you'll cry. If you don't want trouble, don't go looking for it. If wishes were horses, then beggars would ride.
Ignorance is a voluntary misfortune.
It is far easier to start something than to finish it. It never rains but it pours. It pays to be nice. It takes one to know one. It's a small world.
