Let me start by backing your point with proverbs 6:6

Go to the ant, thou sluggard; consider her ways, and be wise: proverb 6:6 kjv

When it comes to observation as a means of learning, it is even recommended by the Bible to show how important it is.

My experience as a result of observing others.

I can administer almost all the injections on my animals not that I was thought all in school, I learnt a great number of them observing those that are doing it.
