I was with my first (and successful) entrepreneurship and I needed the time.
Also I was 100% decided to never use the degree and never work for someone else.
Time invested in studying is never wasted, but I was not learning useful things on the uni and had to come home and study the things I needed and also the things I didn’t need.
It’s all about a trade-off. If you can, keep going. If not, it’s not a waste to let go.
