Fear is important? (IM#122)

It is said that we got to have courage to accomplish extraordinary thing. We are said that we should not be fearful and should take risk if we are aiming high.

But if we aware about our purpose, in a long run, we should be fearful sometimes. And this doesn't mean doing nothing because of fear. It means analyzing situations, combating the problems, inspecting the consequences, and making a leap anyway.
