Are all decisions economic decisions?

Economic factors are very important, but people do sometimes make decisions for other reasons. For example, if I decide to buy a blue shirt rather than a brown shirt, and both shirts cost the same amount, then I have made an aesthetic decision rather than an economic decision. But then, there is first the decision that I can afford to buy a shirt, which is an economic decision. People often choose to do things that will bring them economic hardship, such as buying luxuries that they can't really afford, so economics is not always the deciding factor. People may choose to defy economics, although that is very risky.
