“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”
