When you being a teacher, a tutor, a ...one day University Professor, you need to articulate out every words clearly how you instructing others. Exactly how you receive from your parents, or your peers, or your jobs affairs, that you jealous they could and you cannot?

The communication means, and be really good, and 100% on that exactly the same textbook you deliver the results like you care about it, anything you hear, you learn. Anything you look, you learn. Anything you write, you remember, why you teach others the things, are the decent and righteous. Not just you believing the Gods that simple. 1+1 will always be 2? 

There are the knowledge in the science field.

In the medical field.

In the law field.

In the sporty arena.

There are every books people flip and open and read in their subjective terms, how to get things right. How they read, its from their perceptions what it is the priority in their life. You should just aim higher, the University Professor.
