Steven Pressfield

Never forget: This very moment, we can change our lives. There never was a moment, and never will be, when we are without the power to alter our destiny. This second, we can turn the tables on Resistance. This second, we can sit down and do our work.

Turning pro is a mindset. If we are struggling with fear, self-sabotage, procrastination, self-doubt, etc., the problem is, we're thinking like amateurs. Amateurs don't show up. Amateurs crap out. Amateurs let adversity defeat them. The pro thinks differently. He shows up, he does his work, he keeps on truckin', no matter what.
