My number one piece of advise is to set realistic expectations and speak up when you don&#x27;t think others are setting realistic expectations of you and those around you. This is especially true in the competitive and isolated environments of startups. I have been in many prolonged 100+ hour a week, deadline motivated design sessions that left me in severe burnout.
Everyone has different capacities for this but every human mind has a limit. It starts screaming for things it is not getting sitting in front of a computer monitor for 16 hours a day. My ability to abuse myself like this has dropped sharply as well as I have aged.
