And when it rains on your parade, look up rather than down. Without the rain, there would be no rainbow.
Gilbert K. Chesterton
Criticism, like rain, should be gentle enough to nourish a man's growth without destroying his roots.
Frank Howard Clark
I don't believe in pessimism. If something doesn't come up the way you want, forge ahead. If you think it's going to rain, it will.
Into each life some rain must fall.
Henry Wadsworth Longfellow
No person has the right to rain on your dreams.
Marian Wright Edelman
