It is not bad to get something new and that is better than others, but the most important thing is that we need to think when making plans to get this stuf if it is something that can be afford without one be affected financially. It is a financial mistake for people to strive on what they can't afford comfortably. When one is not financially buoyant to get something that can't bring value, I think it is a waste of money spending huge amount of money just to follow the trend and to feel among of people using the latest.
It is a difficult thing to implement in order to avoid waste, it is necessary to see the goods we buy from the benefits and uses without thinking there, surely everyone will buy what they want, it will affect your income, although the current trend is the need to think in that direction.
