3 key principles:
1. Live in the present
2. Accept the worst-case scenario and try to improve
3. People who do not fight worry die young
I have also applied 2 principles on people skills.
2. Begin in a friendly way.
Though it felt strange at first, it was not too difficult.
Tomorrow I shall add to the list another 2:
1. Give honest, sincere appreciation
2. Become genuinely interested in other people
