Rid yourself of the concept of average.
By not accepting anything average in your life, you send a strong signal to your brain to concentrate on taking actions that lead to success.
Think of a time when you operated at an average level of actions.
What kind of results did you achieve? What opportunities did you miss? What could you have done better or at a higher level to reach your goals?
Observe what average people do and how they behave.
Prohibit yourself (or your team at work) from considering average as an option.
Surround yourself with people who operate on the massive action level.
It will motivate you, and over time you will find that this is the only level of action that feels acceptable.
Let your friends, family, and people at work know that for you average feels like a terminal disease.
