“If the essence of the good lies within us, then there is no place for jealousy or envy, and you will not care about being a general, a senator or a consul – only about being free. And the way to be free is to look down on externals.” – Epictetus, Enchidrion, Chapter 19
The most important job is the one you have right now.
That means doing the best job you can every day.
“I am part of a world controlled by nature…So by keeping in mind the whole I form a part of, I’ll accept whatever happens.” – Marcus Aurelius, Meditations, 10.6
Remember, you are just a spoke in the wheel, a bit player in the drama.
Your job is to play that part to the best of your ability.
Not worrying about when, where, or how the next opportunity will come along.
“‘Well what will my profession in the community be?’ Whatever position you are equipped to fill, so long as you preserve the man of trust and integrity.” – Epictetus, Enchidrion, Book 24.4
You will find your profession.
It is important to have ambition, to want more for yourself.
But to get there, you have to be good here.
If you do your best work now, that next opportunity will come.
