I wrote in the 'War of Art' that I could divide my life neatly into two parts: before turning pro and after. After is better.
Long-term, we must begin to build our internal strengths. It isn't just skills like computer technology. It's the old-fashioned basics of self-reliance, self-motivation, self-reinforcement, self-discipline, self-command.
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.
If you want to send a manuscript, send it to an agent. And send a letter first, asking permission. Launch it into the real world of cold-blooded commercial response, not into the fantasyland of wishful thinking, cowardice and surrender to Resistance.
As powerful as is our soul's call, so potent are the forces of Resistance arrayed against it. We're not alone if we've been mowed down by Resistance; millions of good men and women have bitten the dust before us.
The difference between an amateur and a professional is in their habits. An amateur has amateur habits. A professional has professional habits. We can never free ourselves from habit. But we can replace bad habits with good ones.
