The will to becoming.
To become a professional musician, you must practice.
To become an effective manager, you must follow.
To become a chef, you must cook.
To become is to reach a destination, a mindset, a state greater than yourself.
You cannot achieve such a state without a will, a choice, or a decision to start.
Seneca wrote, "the larger part of goodness is the will to become good."
The larger part of becoming all you can be is the will to start.
