Nature is the best teacher.

Only the strongest survive. This rule of the jungle is applicable to our lives. Somewhere in Africa, a gazelle wakes up in the morning and it keeps in mind it must run faster than a lion. Otherwise it will be eaten. There, in Africa, a lion also wakes up. It's mindful of the need to survive as well. It should run faster than the gazelle. What's there to learn? It absolutely doesn't matter whether you are a gazelle or a lion. When the sun comes up, you have to run. You don't have enough time to think about what to do next. It's not worth composing your thoughts for hours to start doing something. You have to get up and run. Run until you realize that today you are a well-fed lion, not a mauled gazelle.
