Admit it you are scared.
You’re worried and afraid what people will say, losing credibility, tarnishing your image, emabarassing yourself, failing, not knowing what to do, or any number of things.
And fear has your heart pumping, filled with anxiety.
Yet don’t call it fear. Naming it stress.
What you have not realizing is they are both the same. Fear = stress. Stress is just a fancy word for fear.
When you recognize what your stressing about, then, you can make progress against it.
Do yourself a favor and call it what it is. Now begin building the courage to face your fear and conquer your stress.
