Do you believe that human beings need to be challenged to feel satisfied with their lives?

I did a google search of a resident doctor that was recording his life online and apparently he won over 20 medals for track and field events, and I thought it was bizarre he would put so much effort and sacrifice into a financially useless event that provided no economic value to his life, but it seems over 99% of the financially prosperous individuals I find on YouTube live highly athletic lifestyles, and the more wealthy they happen to be, the more athletic they happen to be.

I believed that pretty soon I will be able to achieve my financial goals, and will then be able to live on passive income instead of working for food and materials, but I decided I will need a new mission and challenge if I achieve my financial freedom goal, cause I can't be satisfied with my life unless I am chasing some goal or purpose that keeps me keen and motivated.
