In our environment, we can often see people following one trend after another. They are often afraid of going out of style if they don't. The problem with these, however, is that in many cases they are unsustainable, can be detrimental to our health, or will always keep us financially grounded.
Therefore, in life it often makes sense not to follow every mass movement, but to consider for ourselves whether one or another decision really makes sense in the long run, whether we really absolutely need certain material things in order to be happy, and whether we are not just harming ourselves health-wise and/or financially.
