Hahahaha it's not an easy topic, or rather, it's not easy for those who want to be original in this, since there's been a lot of talk about ups and downs, but I'll say that his statement is somewhat incorrect, given that he compared our lives to peaks and valleys. Life is more like a spiral, along the turns of which we sometimes rise up, sometimes fall down the spiral, if we fail to cope with a turn of the spiral, and some segment of it turns into a mobius strip along which we run, looking for a way to the turn of the spiral leading up :)

If you believe the mountain bees lol, for example, the Caucasian bee that lives in the mountains, it searches for nectar in warm valleys, but returns to the hive in the cold mountains. A beekeeper, a mountain dweller, will consider the valley from where the bees will bring him nectar to be a cornucopia, and the mountain peaks are just a place for his quiet life. He will look at the statement you voiced differently, because, as a definition of life in general, it does not work in the key of ups and downs.
Have a blessed week!
