Oh, it is a fight! You said it right. The first college I finished was a design of market information and now I am finishing digital marketing so I know what are you talking about.
I don't know why but it seems to be harder to work while everything is clean around me. Maybe it's just in my head but there are some psychological facts about that.
Regarding MVP, I so much agree. There are a million things to do wrong and on the other hand, there are users who wants to help you so you don't make a million mistakes. I don't know why people still do those mistakes. Maybe they are so confident and sure their app is going to work just fine.
I will write about user testing in my next post and also will explain everything and show some steps. I will tag you so I can answer your question nicely.
Thanks for reading!
