This is my personal opinion, but staying consisten for me works by making small steps. I am working on several project. One of which is actually making me money. But, yet, I am not stuck with them all the time. I make plans - I plan the small steps for the day on each of my projects and my learning, leaving time also for myself and family, and I execute. Plan + Small steps works wanders. I have time for my kid, for my wife, for the gym. These are important! Regarding the economics study. I would suggest you to quit and do something at least you like. You will never return the time and money you spent, but you can at least stop wasting them in the future. But this is just mu opinion! Depends a lot on your life situation. In my life, I went from Electroncis engineering studies, through microcontroller programming and general programming, to entrepreneurship and finance. It wasn't aways fun and joy, but taking it small, helped. I studied/did what I needed, regardless how much fun it was.
