A woman I know well was promoted to a level way above her comfort zone. She had never failed in the past with her last position, but this new promotion was stressful and a big deal to her. One of her friends gave her this advice:
Just do good work daily and before you know it, it will be a career.”
That is good advice any time you find yourself in a job, or interview for a job, that is way beyond where you expected to be.
Something To Do Today
Do your best every day, and you will quickly grow into the position.
