Setting a goal, no mater how simple is always the easy part. Everyone has goals. The real challenge is not determining if you want the result, but if you are willing to accept the sacrifices required to achieve your goals.
Your performance and ability to get things done is inextricably bound to brain performance. A big, audacious goal looks scary to your brain. And when your brain encounters scary, it goes into “freeze” mode. You don’t want that. If you constantly overstretch yourself, you will lose the required energy you need to take the necessary action to get better.
