True to a point, but I almost sacrificed my mental health, and I did sacrifice my marriage by not sleeping when the kids are sleeping.
As a single parent, now, I have to go to bed right after the kids do. The unexpected benefit is that I'm much healthier and happier. Also I have several full evenings a week with no kids to use for e.g. learning.
I would stay up very late after the kids were in bed, because I was unwilling to give up on the day. This meant I was never around to help in the mornings, and would routinely sleep in 'till 11 or so on weekends, while my ex-wife got up with the kids at 6 am.
This, coupled with reduced income due to bootstrapping a business created too much relationship damage to recover from.
