If money is your sole motivator, I don't think you'll get very far, at least in the startup world.
You should do what you love. Make peoples' lives easier. Financial gain is just a by-product.
Go out and change the world, with a passion to change the world (rather than financial gain), and the rewards (whatever they may be, money or otherwise) will come.
Did I miss how Python fits in here? Seems to be a rather large cognitive gap between the premise and the supporting argument.
The commentary about the "true entrepreneur" has some interesting insights, although it seems a bit religious. We are all organic variable individuals, not Platonic types.
It wasn't there for linkbait purposes, it was there because the startup my friend was considering which initiated this post is crazy about python, another startup in progress is all python-based, and python is always coming up in the discussion. If I wanted to linkbait I would have used a more popular language like Java.
