It’s worth noting the distinction between doubting the work and doubting yourself. An example of doubting the work would be, “I don’t know if my song is as good as it can be.” Doubting yourself might sound like, “I can’t write a good song.” These statements are worlds apart, both in accuracy and in impact on the nervous system. Doubting yourself can lead to a sense of hopelessness, of not being inherently fit to take on the task at hand. All or nothing thinking is a nonstarter. However, doubting the quality of your work might, at times, help to improve it. You can doubt your way to excellence.
