The reason you might be having trouble with your practice in the long run—if you were capable of building a practice in the short run—is nearly always because you are afraid. The fear, the resistance, is very insidious. It doesn’t leave a lot of fingerprints, but the person who manages to make a movie short that blows everyone away but can’t raise enough cash to make a feature film, the person who gets a little freelance work here and there but can’t figure out how to turn it into a full-time gig—that person is practicing self-sabotage.
