I got custody of my oldest girl 20 years ago. Stayed a single father for the next 9 years. It is a real sacrifice and a lot of work to do well. Work hard and do not work more hours than your children can afford. You can learn to live with less stuff. They can learn to live with less you, but is it wise. Build a solid support structure for yourself, you will need it. Friends and family are now more important than before.

I heard once that children spell love... TIME

Sorry, unsolicited advice. Ignore if you wish.
