The bitterest lemon is sweet.
It's the lemon juice, not the lemons themselves, that make life so sour.
Better an ounce of luck than a pound of gold. Better a lemon tree in the yard than a king's house.
A good designer is one who makes lemonade when life gives lemons.
The lemon is an ingenious fruit. Grow it with affection, and it becomes immensely useful.
