Is it not okay to ask for some level of perfection in all the things we do in life?

Think about it: the (Chinese) new year is around the corner. People are dressing themselves up, making arrangements for dinner, and so on. So if anything happens and you don't get what you want, is it bad? Should we be demanding for more? Should we not be happy with a less than ideal alternative? Sometimes, it's better to not ask for more.
