We get into creative work because we have good taste. But there is a gap, what you do is not so good but your taste is good enough that you can tell that what you are doing is “crappy” this is where most people quit. Everybody goes through this phase. The most important thing you can do is to do a lot of work. You create the deadline, it’s even better if someone else is expecting the work from you. It’s only by going through a large volume of work that you will catch up and the work you are making will then be as good as your ambitions.
