I have no more doubts, you have answered everything and all you say makes sense. Those concepts that you present I didn't know, like the sunk cost phenomenon or the fact that using a lot of your creativity wears it out.
I myself know that I can't dedicate myself to this 100%, and that's why I study to be able to exercise a profession. I know how people ignore stories of failure to make this whole world look like something different from what it is. But, the reason why I have been very motivated to achieve this, is that I turned 18 years old and I could finally say that I was the right age to publish creations on the internet (besides Itch asks you to be 18 to do it) so I saw this as the moment where all the years of doing this were going to pay off. But, it turns out that creating story-focused games is so difficult that it takes more than that. Not to mention that the environment I'm in is demanding more and more of me to start generating profits from my work.
For something so difficult and so unpredictable, as much as I want to start generating even a little profit from this.... I will not put my health below my work by any means, and I will continue on the path of taking this with regulation. I will not become a workaholic. I love doing this, and I want to do it in the most efficient and appropriate way. I will take everything in this post into consideration. Thanks for all the comments Redonihunter, to you and others.
