I pretty much share your experience. I have found that this tends to hit me whenever I work alone. Two things fixed this for me ... somewhat: 1. Find and work with someone who genuinely cares about your work to give you honest but compassionate feedback.* 2. Hire someone to do the work for you. This way we give a monetary figure to our torpor. Now there's a hard price for the lack of interest in completing work but the work still gets done. And that's the only thing to get us out of our misery - finished work! - * (I'm not suggesting that one should avoid folks who offer brutal yet honest feedback - no - just saying avoid the patently negative discouraging or jealous feedback. Even though you rationally conclude that envious and obviously unfounded negative feedback does not need to discourage you, they still do!)
