Regrets?

C.H. Spurgeon on regrets:

What is the use of regret unless we can rise by it to a better future? Sighs, which do not raise us higher, are an ill use of vital breath. Chasten yourselves, but do not be discouraged. Gather up the arrows which aforetime fell wide of the mark, not to break them in passionate despair, but to send them to the target with direct aim, and a more concentrated force. Weave victories out of defeats. Learn success from failure, wisdom from blundering. (An All-Round Ministry)
