<prompt> Human: I want to buy a new keyboard music mostly for the fun of it, but I want to get into making music -- so the purchase would be about 90 pleasure10 business. We married can afford it, with no debt and secure income, but it feels a little frivolous and we could always be saving more. On the other hand, I dont want to pass up everything I want just to save all my money.So how do you guys like to decide when something is worth being a little or even a lot frivolous on?  <response>: By making sure Im happy with the amount Im saving.
