I loved the write up, well done. I think, though you are actually working on exactly what Maslow said you should be " Self-Actualization - realizing personal potential, self-fulfillment, seeking personal growth and peak experiences."
Riding the brevets definitely makes you work towards your physical potential, it seems you're gaining fulfillment from these adventures as well. Growth & peak experience seem to be extremely present in your writing as well. I hope you carry on with your rides and your writing and continue to find that feeling of just being happy to be alive, in this moment.
Best,
Eric
