#1 reason-to be with my son (and future children) and not miss any firsts, but can't afford not having an income.
Didn't want to go back to working 2 crappy pt retail jobs and pay someone else to be w/my children.
Have always loved taking care of children-worked previously in a daycare centre and have always watched my friends kids.
Like the relaxed wardrobe.
Like being own boss and not having to deal w/politics/gossip.
I make the rules-hours, schedule, meals.

Basically everything already mentioned
