I can say that the people who say this DO NOT keep an excel on their desktop where every 1st of the month they go around their accounts, investments, etc. and enter the 'updated values' and they see their net-worth growing month-by-month. Money matters (when you are planning your vacations, when you get seriously ill, when you want to buy a new house/car/laptop), etc. Only naive people say that money don't matter. There are MANY things that matter, money is one of them.
