When it comes to finance, I don't think we're all that good at it. ATo be honest, either am I. AFor example, we buy a car because everybody else does. AYet, if we were to use some common sense, leasing a car, something which barely anybody does, is the best option from a savings perspective. AWe're constantly being told to buy this and save that. AUnfortunatelyAwe don't ask "why".
