Courage

Seven little letters.
Strength beyond belief.

Defined as:
The quality of mind or spirit
that enables a person to face
difficulty, danger, pain, etc.
without fear.
I'm not so sure about the 'without fear' part.

It can be that leap from one job to the next.
It can be the grasping of an opportunity
with an unknown future.
It can be the audition just outside your comfort zone.
It can be speaking to someone you admire.
It can be simply speaking up.
It can be standing up to things or people.
It can be stepping back from things or people.
It can be running a marathon.
It can be just one more step.
It is courage.
It is different for different people.
But it exists in each of us.
