As a founder with a family, this has been a tough one for me.
I take Sundays off, but have mainly been working Saturdays.
What do you guys do to balance work and life?
Not exactly work, but I dedicate weekends for learning new skills, which help with work. So, it's sort of work related, but not work exactly.
As for your situation, I can understand that it's very difficult. You can try to time block certain days or hours just for the family. And unless something is really burning and crashing, that time is for your family.
And the time block doesn't always have to be weekends.
Saturday is the only day I actually try to take off fully.
Building my startup has been a ton of work, but it's really exciting and doesn't feel like "work" per se.
