I don't think it was thought of that Facebook would be worth $1.5T some day, but I'm positive what was on the 10th employees mind while getting paged at the middle of night was "I'm in the process of getting filthy rich". That certainly would help me focus.
Facebook was a networking site for a handful of college campuses at the time. It had some great traction, sure, but I doubt "filthy rich" was a serious expectation among employees.
Boz joined in 2006. In 2005 their valuation was $100M. In 2006 their valuation was $500M. Literally all the people he sat next to when he joined all knew they were filthy rich already.
