“We can’t help what we like.”
Sure we can.
Deciding to like or not like something is way easier than trying to force yourself to act opposite of your desires. When I was a teenager and living on my own, money was extremely tight. I needed to make cost-efficient choices when it came to necessities like food. Until that point in my life, I hated peanut butter. But it’s cheap, calorically dense, fairly nutritious, and doesn’t require any particular kind of storage – perfect for a kid living in shaky circumstances. The only problem was that I couldn’t stand the stuff.
But it was the right choice, so I decided to like it. Not “I decided to eat it even though I didn’t like it,” because that sounded like torture. I just decided to like it.
Now I love the stuff. People hear that story and think I’m weird, but I think most people just haven’t tried reprogramming their desires. All it ever took for me was thinking about the act or object, skipping the middle part where I thought about how it felt, and then thinking hard about the other side – how it felt when it was over.
So for peanut butter, I’d look at the jar, and not think about the taste – which is fleeting and inconsequential anyway – and instead think about the end result, and how much I like having a cheap, easy, portable, nutritious way to feed myself. Boom, I like this stuff! I could think about that even while shoveling spoonfuls into my craw, and the deed was done. My brain was now wired to like the stuff. How it tasted was just a manifestation of that.
It’s the same with soda. Soda is absolutely terrible. It’s pure poison, and don’t let anyone tell you differently. All I had to do was think about how vile it was, and it suddenly made me sick to my stomach instead of tasting good.
The point is, it’s not a question of willpower, or of forcing yourself to do stuff. It’s just a question of deciding why you like things in the first place. You’re not an animal, led around entirely by your short-term sensory input. You can take the little wire in your brain that connects “what you like” to “why you like it,” and unplug the “why you like it” end from your sensory organs and plug it into your reason instead.
Give it a try. It might not be as hard as you think.
