I don't know why by I have little difficulty not spending my money. (a) Almost every time I want to spend money the shops do not have what I want. (b) Almost every time I do actually spend money (usually to replace something) I find out the new item is such crepe that within a week I revert back to the old one or make do without.

Can anyone hazard an explanation as to why I could have such a different mentality to another person who is the opposite, i.e. (i) anything they see in the shop, the think it is "cool" and they "need" it; and, (ii) every time they buy something..........well two things might happen I guess, (ii.1) they ignore the fact it is crepe and just find something else to buy, or (ii.2) they don't see it as crepe because they have low expectations.
