Lately I have developed habit not to buy stuff I do not need. Its always tempting to buy new clothes and it kind of brings this happiness. Or buy a new phone because a new model has arrived and the one that yiu are using is already outdated. But as long as it works. The phone should be used to its fullest life. Until the phone is so old that it can not be used anymore. Its not about catching the trend its about how much waste of resources the mobile phones are.
