I shoot for 10 but honestly get more like 6-4 hours a night with 10 hour work days which I refuse to work past Thursday giving me 3 day weekends. I can tell you I have one of the most happy women in my life.. She came from a well funded family.. Her last husband worked all the time, gave her and the kidseverything, but was mean to the kids and never spent time with the family.. I am the opposite always believed work smarter not harder. Let me just say I get more sleep than him and he might make more than me. However, I've managed to have a better place and she is happier with me and her kids as well..
