In my opinion, studies are an investment both mentally and physically. We invest ourselves in our minds, we think about more or less important and more or less complex issues every day. We invest ourselves socially, a respect is established for the proper functioning of the school in our class. For the less fortunate among us, even though we are all part of it, it can be a moral investment. It is a difficult thing to live every day with people we don't like, or to suffer from school phobia. And finally on the physical level, for example during sports classes or the backpack that weighs on our shoulders every day. We are talking about several kilos, the kilos of our knowledge.
