My boss (Academic scientist) told us that we had to work a 70-90 hour work week to be successful in this business. I found that funny as I don't count my productivity in hours work, but in the amount of "product" I produce. "Working hard" shouldn't be a function of time, and I think more people need to appreciate that. This tends to be a little more difficult for people to do however, as it typically requires a lot of hard work up front. For example, it took me a month to figure out how I could make a 45 minute procedure turn into a 7 minute procedure while still maintaining the same quality. But I got it working and I can do 6 times the amount of work in the same amount of time.My free time can now be spent doing other things, such as working on a startup:) People just don’t do this for some reason. Put the initial investment into what your working on, make it as efficient as possible, and then reap the benefits while being productive AND having enough time to post cat videos on facebook:)
