Is nearly everything we do in life mostly just to find a potential partner?

Things like being highly successful in sports, having a good career, having really good hygiene etc etc. I ask this because I didn't really know why I was so fixated on being a pro runner, I did like track and running, but then I realized that the main reason was really that I wanted more attention from the opposite gender. Once I realized that I feel that my motivation for the sport dropped a lot since I didnt want to do it for women anymore. Especially because I had a potential relationship ruined and caused me great pain. Is this the same for you?
