Doubt is your friend.

Don't believe everything you think.

Don't believe everything you hear or are told.

And if you want to grow, don't believe everything you believe.

Question it periodically.

Why do you believe what you believe, and does it actually still serve you, or hinder you?

Muhammed Ali once said,

"The man that views the world at 50, the same he did at 20 has just wasted 30 years of his life."

Often we are prepared to argue, fight and die for what we believe and know.

But knowledge (as information) is often, incomplete, inaccurate or incorrect.

It is far from "the truth."

Knowledge is borrowed.

Wisdom is your own.

Don't underestimate the power of doubt.

Doubt will set you free.

Question everything.
