A wild horse is a beautiful thing on its own, but isn't very useful to a person. To create a symbiotic relationship with the horse, the owner must break the horse, training it to give up some of its wild instincts and replace them with conditioned responses.
I rode a horse a few weeks ago in Chile. She was generally well behaved, but had her quirks. Sometimes, riding along in the desert, there would be a tasty looking shrub. If we were walking slowly enough, she would stop and eat it. I'd have to yank on the reins to prevent her from doing it, but that didn't stop her from trying again next time.
It feels like my brain is the same way. I train it over and over again, but it's never completely broken. There are battles that I fight every single day, knowing that winning doesn't mean eliminating those battles entirely, but just winning them more often than not.
One of those battles is the desire for pleasure. I can logically want to live a fairly ascetic life, can enjoy that life, but still there's some draw to temptation. I want to do fun things. I want to buy things I don't need. And after two of my good friends have met serious boyfriends/girlfrends on Tinder-- I really want to install that app, even though I'm not dating until WifeQuest begins next year.
