"It's of no use to look back and say, "I should have been different." At any given moment, we are the way we are, and we see what we're able to see. For that reason, guilt is always inappropriate."

Certainly. But take this into consideration: of every ten problems we have, nine are created by our own selves - through guilt, self-punishment, self-pity. However, from time to time a great obstacle appears in our path, which was put there by God, and which is there for a reason. The reason is: to give us the opportunity to change everything, to move forwards.
