You can have things.
Or things can have you.
If you work to fill in your house with things, things have you.
If you work to buy the latest gadget, things have you.
If you cannot stand having an “old” car or phone, then you belong to your stuff.
If you must buy clothing from every new season, you are a slave of consumerism.
If you don’t spend your money on expanding your mind and your heart by learning new things and knowing people that are interested in you for who you are, not for what you own, then you are wasting your life.
