Ecclesiastes 11:4-6

Those who wait for perfect weather will never plant seeds; those who look at every cloud will never harvest crops. You don’t know where the wind will blow, and you don’t know how a baby grows inside the mother. In the same way, you don’t know what God is doing, or how he created everything. Plant early in the morning, and work until evening, because you don’t know if this or that will succeed. They might both do well.
