Thank you very much!
My detailed answer will probably take us beyond the scope of 3D art and beyond the scope of art in general. I’ll try to limit myself to them. Although this applies to everything else in our lives. 
At some point in my life, I began to realize that when drawing or modeling, I too often follow my fears, and not so often my desires. Here are a few examples that motivate me to do things I don’t want to do:
- What will those whose opinion you trust say when they look at your work?
- You need to draw and model so that people want to love your work.
- If you do it this way, people will not understand you, will pass you by and you will remain outside the mainstream.
- What you want to do is ridiculous and uninteresting.
- Although you want to do exactly this, you repeat yourself. This is bad for…
I noticed that by following my fears, I did not enjoy what I was doing. Although it seems that fears tell you useful information. And vice versa, when I “let go of the reins” and forgot about fears, following only my desires, I received great pleasure from the work itself and from what came out of it.
This is the method that I now try to follow. Listen to my desires, which actually come from nowhere, and be able to distinguish them from my fears.
In fact, it is deeper than just a method of creating works of art.
