i dont have kids and my girl friend is a tattooer as well( which helps sometimes) but i run a shop with 6 fulltime tattooers and work at 3 different shops 2 days a month. my weeks are 6day weeks....
as much as i am "taking care of business" most of the time i am awake i can relax so easy by just sitting and watching some bshit on tv. but most important for me is to realize everyday that the act of tattooing is not what stressed me out. it is all the bshit around it. appointments, customers, co-workers......so in the moment i put that needle to the skin i try to enjoy it.
