Fear.

Fear is yet just a thought, are minds creating something that isn't there and why we are afraid of are own thoughts is because we don't understand or know anything about them.

Your not afraid of the dark your afraid of what's in it,your afraid to see the truth of your imagination or the lies of it.

Your not afraid of heights your afraid of falling.

You don't have staged fright your afraid of failing every one.

Your not afraid of dying your afraid of the pain before death and leavening your loved ones behind.

But the biggest fear that you will ever have is that you will have to conquer your fears.

But if you take control of your imagination so it doesn't control you you can conquer anything. No matter what the fear is.
