"Nobody tells this to people who are beginners. I wish someone has told me. All of us who are in creative work, we get into it because we have good taste. But there is a gap. For the first couple of years you make stuff, it's just not that good. It's trying to be good, it has potential, but it's not. But your taste, the thing that got you into the game, is still killer. And your taste is why your work disappoints you. A lot of people never get past this phase; they quit. Most people I know who do something interesting, creative work went through years of this. We know our work doesn't have this special thing that we want it to have. We all got through this. And if you are just starting out or you are still in this phase, you gotta know that it's normal and the most important thing you can do is do a lot of work. Put yourself on a deadline so that every week you finish one piece. It's only by going through a volume of work that you will close that gap, and your work will be as good as your ambitions. And I took longer to figure out how to do this than anyone I've ever met. It's gonna take a while. It's normal to take a while. You just gotta fight your way through."

Start small. Big projects are just a whole bunch of small projects combined together.

Practice techniques. Don't be afraid of spending time on the fundamentals. For example, at some time, most artists have created a sketchbook full of lines, straight lines, circles, curved lines. Once you have mastered the basic techniques, you can see better how to do a project.
