> Does a flower stop being pretty just because you don't expect or desire it to be pretty?
Sometimes. If I didn't desire it to be pretty, then I may have never planted it. By not desiring it to be pretty, we limit ourselves to enjoying only those flowers planted by others or by nature. Maybe that's enough. Or maybe there's less in the world to enjoy when so many people stop desiring to enjoy. Or maybe our appreciation for the beauty of a flower is simply heightened when it's the fruit of our investment in planting and nurturing it, which was motivated by our expectations and desire for it to be pretty.
> It may also be stamped upon in the next moment by a passer-by.
It has less chance to be trampled if my desire for it to live motivated me to take measures to maximize its chances of survival, such as planting it in a garden where it's less likely to be trampled, or watering it, or giving it better soil in which to grow.
There are probably good lessons to be learned from both points of view. Having expectations may be the necessary evil that drives us to change things for the better. But it also makes us less happy when they don't pan out. In fact, I think that's the message in the many sayings about changing what we can and accepting what we can't.
