3. Toxic People

Successful people believe in a simple notion: you are the average of the five people you spend the most time with.

Just think about it—some of the most successful companies in recent history were founded by brilliant pairs. Steve Jobs and Steve Wozniak of Apple lived in the same neighborhood, Bill Gates and Paul Allen of Microsoft met in prep school, and Sergey Brin and Larry Page of Google met at Stanford.

Just as great people help you to reach your full potential, toxic people drag you right down with them. Whether it's negativity, cruelty, the victim syndrome, or just plain craziness, toxic people create stress and strife that should be avoided at all costs.

If you’re unhappy with where you are in your life, just take a look around. More often than not, the people you’ve surrounded yourself with are the root of your problems.

“You’ll never reach your peak until you surround yourself with the right people.”

4. Fear

Fear is nothing more than a lingering emotion that’s fueled by your imagination. Danger is real. It’s the uncomfortable rush of adrenaline you get when you almost step in front of a bus. Fear is a choice. Successful people know this better than anyone does, so they flip fear on its head. They are addicted to the euphoric feeling they get from conquering their fears.

Don’t ever hold back in life just because you feel scared. I often hear people say, “What’s the worst thing that can happen to you? Will it kill you?” Yet, death isn’t the worst thing that can happen to you...

“The worst thing that can happen to you is allowing yourself to die inside while you’re still alive.”
