I will assume your post is serious. But honestly, when you look back on your life and you skipped out on the holidays, are you going to be happy that you were working and not spending time with whatever family or friends you have? Even if you don't, when you look back on your life, do you think that skipping the 6 or 7 days for a "holiday" are really going to have had a huge effect on your life?
If you are the founder, you are much more invested in the business and are willing to skip the holidays.
For sure, your co-founders may have family that is more important. As much as you might think it is okay that people should work everyday without a day off, it is better to have a little time off. Do you really think that things will "succeed or fail" if they don't have that time off?
You should read or watch the Charles' Dickens' A Christmas Carol.
Enjoy your life. Not everything has to be about work and making money all of the time. I mean... it's nice to do and a lot of people have accomplished that dream, but it's also okay to enjoy the holidays off from work.
