That's true, as I said above, I majored in photography, worked in a coffee shop, but my interest was in the world of mechanics, this didn't spread. but because it was to improve my financial situation, I did what I found as work.
It does not necessarily have to be that gloomy. Of course to make ends meet, we all have to do things that we are not proud of but dont let that weigh you down.
Maybe in the near future you will be able to save your earnings from the coffee shop job to start your own joint promoted with the help of your own clicked pictures and then get that mechanical degree down the line and use that build the next state of the art coffee machine?
Or maybe not, but that dont matter, what matters is that your tried to live life your way.
