Talking of morning exercises, Marcus Aurelius used to remind himself in the morning that he would be around exactly the kind of people you describe, but that they did not have the power to make him crazy if he is aware of their inevitability: http://classics.mit.edu/Antoninus/meditations.2.two.html (BTW: I only used this source because it seems to be public domain and available online, if you want to read translations of ancient texts, invest in a modern one that is more convenient to read.)
(1) Of course, if you start your own company, you will be dealing with things you can't control as well.
Edit: Replaced asterisks that made the text italics.
