The other day I asked everyone working for me this summer what they're working for. Almost everyone gave me the same answer: "I'm saving to buy a car." There's nothing wrong with that, but I was hoping to hear things like I'm learning a new skill, I'm starting a business, or I'm investing in myself. A car loses value. You don't.
I see the exact same mindset in betting. Most people are obsessed with making money, not with becoming better bettors. They never study, never review their mistakes, and keep repeating the same decisions.
That's why they keep losing. If your goal is to make money, you'll repeat the same mistakes. If your goal is to evolve, the money becomes a byproduct.
