Is it bad to idolize material things?

Well, i believe some things we need to have that are material things we need but not iodolize things that are very important to us for example i need my cell phone cause i don't have no home phone service cause i find it useless... I need my Laptop computer in order to communicate with friends online and go on my websites ...But useless material things like getting new clothes all the time is no good , sure we need new clothes but wear what we have and use them up than get new things ... I am wearing shorts that are 3 years old , they still fit and not worn out so I'm wearing them... But i am not a big spender never brought up with lot money and we had to settle for what we had and we never asked my Grandparents for School Clothes money cause we didn't want do them things.
