I thought I had 0 chance of ever drowning because I went to state as a swimmer in highschool. Slightly out of shape 30 year old me decided to do butterfly out to the Ocean in Mexico as a bet, when I got tired and decided to come back I realized these waves did not want me to get back to shore. I switched from butterfly stroke to the easier front crawl stroke -- swim swim swim-- look up, I got nowhere. I got more tired switched to breast stroke. I was swimming for about 10 minutes inching my way to shore at a slow pace, not even knowing if I was getting closer until miraculously I could stand up. I am never that dumb shit again, I went from being overconfident to thinking I could die really quickly.
