Things We Don't Need

I think we spend too much money on things we don't really need. For example, I bought the last mobile model. It's very cool, but really unnecessary. I also spend a lot of money on brand brand name clothes. Or worse still, my friends buy cheap and bad quality clothes, of course, always in style.

I think we buy because we don’t know exactly what we want and we fall in  (There are several ways to say what you mean: ¨fall prey to... (common English expression)¨ or ¨are persuaded by...¨)  hidden persuasions of  the hidden messages of big stores. Moreover, we believe we choose a product when in fact we are being induced by what we see on TV. 

If we chose more consciously we could save a lot of money that could be used  to for more important things, such as (¨such as¨ or ¨like¨) know value items and things to improve our health and quality of life.
