Sooner or later you will know if your lifestyle is wasting your money, just keep doing what you do best, if you are wasting money on friends and wasting your time you will end up getting wise one day when you are completely broke,   continue.

You don't have to be warned about how you are spending your hard-earned money, my uncle used to say that money is hard to get but easier to spend, you work alone and people spend your money with you, I have never seen where those that spent out of your money decide to join you at work, or have you?
