Yes, I've also heard the mantra that when you serve others, then the money follows.

I'm not sure how I feel about that.

In a karmic sense, yes, it does work, but I can recall two specific cases where I had "business partners" with whom that did not work. That is, I didn't feel I got paid directly for my efforts.

But then again, I did learn some fundamental skills about business and people in general, and a few years later, I went on to do very well, so in a more indirect sense, I guess I did gain from it.

It's a big subject, though. I would say that the best way to do it is to serve others without any attachment to what's in it for you.
