Now, just as “b’derech she’adam rotzeh leileich” works for health, it also works for wealth. If a man wants to become rich — it may seem surprising — in most cases he will succeed. If you want the source, look in Mishlei. Mishlei is full of advice on how to get rich. Now, of course, Mishlei is a mashal (parable). Everything there is talking about the real wealth — wealth in spirit and Torah. But in Mishlei the mashal is also always true. For instance: “v’yad charutzim ta’ashir, the hand of those who are diligent is going to become rich” (10:4). If you will put in work — be diligent and devoted to your business — you will succeed. If a man is always taking off — if there is always a sign on the door, “We’ll be back at 12:15” and he is never back — this man will not succeed. That is a rule. Hashem follows that rule. “Yad charutzim ta’ashir” means that wealth depends on a person’s efforts. You will not become wealthy by being lazy. Sometimes a man wins the sweepstakes without trying. Sometimes people try very much and they lose everything. But, in general, if you will observe how things go in the world, it’s people who are trying hard who are the ones making money. Now, this may seem unorthodox to ma’aminim, but you have to understand what emunah means. Emunah means b’derech she’adam rotzeh leileich. Do you like wealth? Molichin oso — you will be led toward wealth.

But you have to like it. If you just say you want wealth but will not do anything for it, it’s like a man who says, “I want to be a talmid chacham,” but he never opens a Gemara. The same applies when it comes to money. You have to try very hard to become rich. In short, the great principle of b’derech she’adam rotzeh leileich applies even to gashmiyus, material life. If you want to go in a certain way, molichin oso, you’re going to be given success. If you sincerely try to live a successful life, then Hashem will give you success. That is a promise. And it’s logical, too. You have to realize that Hashem wants nothing more than your success in both worlds. Hashem not only wants you to be happy in the World to Come, forever and ever, but He wants you to be happy in this life. That is a fundamental teaching, which we should never forget for a moment. This great principle is so pervasive that it applies even when a man wants to do something that is not good — even then he will also get help from Hashem! That is how far this principle goes. It’s a remarkable thing! Even if a person wants to do an aveirah, he will get help from Hashem! Where do we learn this? From Bilaam.
