I think striving to be rich is great. I strive to be rich. I may not make it, but if I do, it'll be by earning it. If someone dumps a hundred mill in my lap, though, it would turn me into something worthless. Perhaps you, and many others here, are made of better stuff. But, I know my tendencies and I'm best off working.
We are made out of the very same stuff. You’d be fine. You’d take care of yourself. Nothing will ever make you worthless. You are very worthy indeed.
