For each person you interact with frequently, look for the one great behaivor/attribute that you can replicate and use to evolve.
People are incredibly complex and interesting. Older people have more memories, backstory, and most importantly they have build behaviors over time that work well for them.
It reasons to assume then, no matter your overall impressions of the people around you, there is likely at least one great attribute you can replicate from each person you meet.
