You are not falling behind. If you haven't touched your WIP in weeks, if you haven't come up with a new idea, if you haven't gotten your book done and it's been 3 years, it's okay. You are not falling behind. Unless we are obligated to reach a deadline, we begin to believe that we are failing. We see countless people finishing their projects, selling their books, succeeding in the field you're in. And it's hard not to compare yourself to them, you're similar but they are doing the work, and you haven't written a paragraph in over a month.
Comparing yourself to others is a downward spiral that will never give you satisfaction. It's a difficult thing to try and overcome or ignore, but you have to. Instead of seeing other people's victories as a failure on your side, try and see them as goals. Goals to reach, inspiration to get back to your WIP, write that paragraph, or finally try and finish that book.
There is no secret that they know, and you don't. They aren't worse or better than you. There is no right answer. No finish line you need to cross. You work at your own pace, create goals to strive to and try not to compare your progress to others. Enjoy the process!
