I definitely experienced this at the last stages of my first startup. In my opinion, your own psychology is probably the hardest thing to manage. Ben Horowitz refers to this stage as The Struggle. He talks about how when you start your company you do it with a clear vision of how success looks like. You are going to create an amazing company with the smartest people, build a great product and make the world a bit better. After working day and night, you realize things are not going as planned. The market isn't quite what you thought it would be. Your employees are losing confidence, some are quitting. You are running low on cash. You lose a loyal customer and walls start closing in and you find yourself in the struggle. The struggle is when you wonder why you started the company in the first place. When you are in the struggle nothing is easy and nothing feels right.
