Early in my career, I used to be very demanding of myself. It was hard for me to accept when I made mistakes in life. I remember one day, I was working on a woodworking project in my garage, and I got upset from making mistake after mistake. I got so mad, I eventually picked the project off my workbench and literally threw it against the wall. Afterward, I took a moment to calm down and wondered how unpleasant and expensive woodworking could get for me as a hobby if kept I reacting like this to my mistakes.
