In the book, Turning Pro, author Steven Pressfield talked about what separates amateurs from professionals and how a professional became who they are.
I will write about what these aspects mean to me personally.
The professional has compassion for herself
The pro knows when to urge the followers on and when to back off. The pro leads by motivating his followers to want to achieve more.
The professional lives in the present
The pro knows the most important moment is the present. He does not live in the glory and fear in the past, and he has no need of the distraction of living for the hope in the future. Capitalizing on the moment right now is what matters to the pro.
The professional defers gratification
The pro does not allow instant gratification to be the distraction and a weapon for the Resistance. The pro focuses on the how-to and leaves the what and why for someone else to worry about.
