The crucial role of his thinking
What makes you different from others? Is it your looks? Is it your interests or your hobbies? Well, yes to some extent, but more than anything else: it's your brain. Your brain contains your memories, your goals, your desires, your beliefs and pretty much everything that makes you "who you are". It's also what controls how you think, how you plan, and how you react in any given situation. It is the brain that makes the difference between the average person and Steve Jobs, Albert Einstein and Elon Musk. If you want to enjoy the kind of success, money and lifestyle of the world's most successful people, you have to think like them.
If you're not getting what you want in life and you feel like you're hitting the wall in your business, your relationships or your finances, the problem is almost certainly originating in your brain.
The way you think, your creativity, your intelligence... all come from the physical makeup of your brain and the way you approach problems. The best way to approach any problem is to approach it at its root and at its most fundamental level.
