If you dislike riding a bike, I'm not sure that there's anything that anyone can possibly say that will convince you otherwise. If riding your bike is misery, then walk. Or use a scooter. Roller blades. Skateboard. Pogo stick. Unicycle. Get an e-bike so you don't have to pedal. Life is too short to force yourself to do stuff that you hate. That's fine. Everyone has different tastes and preferences.
I dislike driving a car, too, but I do that every damn day without complaint. Walking, or roller blades, or a pogo stick will never make an effective replacement for getting to work. Isn't that what this thread is supposed to be about, biking to work? It's about transportation to a place I need to go, to make the money to support my life. If life is too short to do things I hate, I shouldn't be driving either, or going to work at all for that matter. Given that I need to get there, a bike might well be the least objectionable option. If I could get that far, which I currently can't.
Walking is more pleasant, which is why I have trouble motivating myself to ride shorter distances, but I'll never be able to go 4 miles if I don't practice going 2 miles. That's why I need help with motivation. Is that really so strange? I'm not asking for some magic words to make me like biking. Just trying to find a reason to do it anyway, like any other chore.
As far as the rule #5 thing . . . You're starting out on a path to self improvement. You have a long way to go. It's a mistake pretending that it's always going to be easy. Anything worth doing in life is going to be a bit of a struggle. It's going to be tough. There will be times where you're hurting and have to keep going. There will be times when it's pouring freezing rain, there's a wild headwind, and you're miles from home. There will be times when the hill beats you, when your bike breaks down on you, when you crash and lose some skin. You are capable of overcoming all of those challenges. Doing so will make you stronger and more resilient. You'll be able to draw satisfaction from the fact that you were able to motivate yourself through the hard parts, and when you get one of those fun bits of cycling (the gorgeous sunny days, the downhill sections, the many little oddities and adventures that you find) you will know that you've really earned them.
I know it's not going to be easy, but you're mistaken that my goal is self-improvement. My goal is to be able to get to work without burning fossil fuels. I'm not doing it for the sunny days, the downhills, and the other 'fun bits,' though I'm sure I will come to enjoy them with time. I just can't use those as the motivation to get through the hard parts, because that's not the point for me.
So what, I just give up and drive because biking isn't inherently enjoyable to me? That's a hell of a cop-out. Pretty anti-mustachian, too.
More importantly, Rule #5 is not "Keep working at it, it'll all be worth it when you get through." It's "Harden the fuck up." Telling someone with a motivation problem to suck it up is not exactly motivating.
