I think that Ikigai for us (athletes) is already in our mindset, we are already thinking about what we want to do of our lives and I guess that the majority knows what they want to do!
In my point of view, Ikigai's philosophy is the routine of athletes.
We are passioned of a sport that we love, where we are good at, the idea in the future is to get paid and with our sportive career we will help the next generations and push the limits of the sports.
In my case Kitesurfing and all the things that are around this sport (trainings, competitions, learnings, travels, meetings, opportunities, etc) are my purpose in life!
