Professionals adhere to a practice, which is a strict, prescribed regimen for raising one’s mind and spirit to a higher level. Writers, yogis, bankers, and directors are all examples of this.
Practice elements include:
A space is a one-of-a-kind place to rehearse your craft.
A period in which you work on your craft
An intention: to improve, to go deeper, etc.
There is no end point to this practice.
