failure is the mother of success.
false friends are worse than bitter enemies.
far from eye, far from heart.
far water does not put out near fire.
faults are thick where love is thin.
fear always springs from ignorance.
fields have eyes, and woods have ears.
fire and water have no mercy.
fire is a good servant but a bad master.
first come, first served.
first impressions are half the battle.
first think and then speak.
fools grow without watering.
fool’s haste is no speed.
fools has fortune.
