But recently I realized the value they have. Humans need cycles and renovations. They need to get to a point where they can look back to what happened and what didn't in their lives and plan for the next cycle to make better. They need celebrations to allow them to relieve important moments and to realize that time is passing.
We celebrate not because the day itself has any special meaning, but because every one of us can get a special meaning out of it.
I was already coming to the realization, but the turning point was when a friend of mine told me her experiences working in countries close to the equator, where seasons and cycles don't exists. There, the culture is to live by the day, because winter never comes and they don't need to prepare for hard seasons. If they are hungry, fruits are always available, food is always provided by nature.
For this reason they don't plan ahead at work, they don't save money and they waste a lot of resources thinking that there will always be something provided to them. This was her hardest problem in working in those cultures.
So, these cycles shape cultures and are a big part of what pushed mankind forward. Now I look at them with different eyes.
