How did you deal with the stress created by meeting the challenges?

There are three things that helped me to handle stress during the challenges. The first thing was to focus upon the details of the problems you set and to decide upon the steps that would be necessary in order to solve them. That provided a quick sense of progress, which lowered the tension. You will have noticed that I was also prone to making light, mostly self-deprecating jokes about the situation or issues that arose, just to make my other teammates smile. The third thing I did to defuse stress was to take two-minute breaks at the end of each challenge for focused breathing exercises. These helped enormously.
