Love posts like this. Real thinkers.

I think the greatest words that can be said by any person are...

"I don't know."

If you can admit that you don't know you simultaneously realize that you need to learn. You are not afraid to be judged for not knowing the answer to something. It is the purest honesty as you have just rejected the opportunity to bullshit your way through something and save the precious ego or reputation you think you need to uphold. If a person cannot say this simple statement, they are incapable of honesty, IMO, based on all the life I have blown through already.
