Fear

Humans have fear beause it stops you from making the wrong decision,

Sometimes it stops you from making the right decision,

When you are brave you are scared but you do it anyways,

You have the power to stop fear,

You are stronger than fear,

If you don't do something because of fear then you haven't tried, you haven't learned, changed, made a difference, grew, you just gave up, 

Fear can help you, ruin you, but it can't take control of you unless you let it.
