Ask HN: How to combine work, entrepreneurship and having a life

Hi HN, I'm an electronics engineer and I work in that field, and I also have a side project and a life, haha. I'd like to know how you manage to achieve balance. It seems really difficult and feels like I'm constantly juggling. I'm not as involved with my family, friends, girlfriend as I'd like... I feel like the project isn't progressing as I'd like after three years. Any advice?
