You have nothing to feel guilty about. Sometimes it helps to think of money as expansible rather than a fixed pie. (I know this is hard, and sometimes fantasy, as sometimes income *isn’t* able to be expansible.) But you are more likely to make connections (in either people or concepts) that eventually increase your income and make your life richer if you spend this money and go rather than save and stay away.
Think of it as like mulch for a garden, or something.
