Knowing more doesn’t matter in the long run; learning more does.
The thing that is going to set you apart is not that you already know; it is that you are willing to learn.
Knowing might get you going, but it won’t keep you going. As you progress, there is no way you will know how to do the things you will need to do. This is where most people will stop. Doing the unglamorous work of learning what is unfamiliar is the thing that guarantees your success.
Where is it time for you to put in the effort learn something new so you can go the distance?
