Elon  Musk recently said he works 120 hours a week. That’s 17 hours a day or pretty much every waking hour (if you factor in 7 hours sleep). It got a lot of press with people saying how crazy it was. These people are obviously not #entrepreneurs. 17 hour work days are common just not for 7 days in a row. My work week often includes 17 hour days and I easily average over 80 hours a week in any given month. 80 hours a week is not even 12 hours a day. Hell, you can put in 13 hours a day, have 4 left over for free time, take Sunday off and still have put in 80 hours. If only we could really build an empire in a “4 Hour Work Week” like Tim Ferriss. 😀😀
