Learning how and when to censor yourself is very important when developing any artistic skill. The way you go at this process can have a huge impact in your skill. I try to keep my learning curve steady and steep, in a way that actually makes it enjoyable and worthwhile. In that sense, it’s important to allow myself to go in different directions, and knowing when an experiment is proving worthwhile.
I see a lot of people telling themselves that their work is not good enough. Most of the time, that’s just not true. There is always something worthwile to be found, even if it’s hard to spot at first. True skill lies in laying that something bare, stripping it of all fat and needless filler, and be confident enough to put it out into the world. That skill is what makes true artists.
