Agree with everything said about taking your break, but I think you also should set your expectations properly. 2 years without a vacation when starting a business is not so much, it's actually pretty standard I think. So are 80 hour weeks and everybody else in th company making money except for you. I don't know any successful entrepreneurs that are not complete workaholics.

This "grin and bear it like a big boy" attitude is toxic IMHO.

If you assume that 80 hours weeks are neccessary, you will work 80 hours long weeks whether it is needed or not and whether it is actually effective or detrimental.

There are lots, they just also aren't egotistical maniacs who need to let everyone know how pious they are.

If you want a really high profile example: DHH from Basecamp.
