I'd now like to combine the two and encourage you to stop asking the question: "How much money can I make" and instead turn the question on its head and ask: What's the minimum amount of money I need to have?
The benefit is that once you successfully answer the latter question you can turn your attention to the much more important question of "What else drives my life?"
My guess is the answer isn't money.
So here's my question to you: Why don't you start thinking about these things?
P.S. If you doubt the benefits of this approach I invite you read this recent post of mine, Why I Can Still Smile After Making a $25,000 Mistake (Really).
