Study the negotiation patterns of others

Every time you struggle to decide on something with other people, think to yourself “I’m negotiating”.
Then, consciously observe how the negotiation develops.

Observe the different approaches of each side involved
Are they soft or hard negotiators? Are you more soft or hard in this negotiation?

Once the negotiation ends, note down the participants and give each score between 1-10 on the “soft” and “hard” negotiation methods
Revisit your notes weekly to quicker spot negotiations in your life and understand if you and the people you know tend to be “soft” or “hard”.
