Fear can be paralyzing and motivating at the same time.
It can be paralyzing when you think about the short term.
Short term fear such as the fear of failure, the fear of making a fool of yourself or the fear of being wrong.
But it can also push you when you think about the long term.
Long term fear such as the fear of not having done enough, of not having lived up to your potential and of not having given it all you've got.
It can paralyze you.
Or it can push you.
What it does to us (or for us), is ultimately up to us...
