Just stumbled upon this nice video comparing ape's social dynamics with human. At least interesting IMHO. Basically the findings made in this video are not so surprising, though repetition is the mother of learning right?

- Be big or make yourself look big (in our would I would say be in shape)

- Master social interactions (especially the first impression)

- Dominate more space around you

- Control your voice (people need to hear you, speak loud enough)- Stay calm (especially under pressure)- Don't be passive, take action
