Haste makes waste. Too many cooks spoil the broth. Out of sight, out of mind. A rolling stone gathers no moss. The early bird catches the worm.
Prevention is better than cure.
An ounce of prevention is worth a pound of cure. Early to bed and early to rise, makes a man healthy, wealthy and wise. Stuff a cold and starve a fever. An apple a day keeps the doctor away. Prevention is better than a post-mortem.
