Look around your room.
Look around your home.
Look inside your weave closet.
Do you see any clutter? If so it's time to face the facts: all that clutter used to be money! And all that money used to be time!
There is NOTHING wrong with spending your money on the things you want; but if you're spending your money on things you THINK you need because you're following trends or you're trying to win someone's approval then you need to rethink some things.
If your space is filled with stuff you don't need, re-evaluate whether your spending habits are serving you or not.
