Tom Swerts's Key Ideas from How to Win Friends and Influence People
by Dale Carnegie

Principles

1. Don't criticize, condemn, or complain.
2. Give honest and sincere appreciation.
3. Arouse in the other person an eager want.

Attitude: Empathy

Being empathetic is a deeper, more visceral and emotional response than mere sympathy. Sympathy is to feel something for someone, but empathy means to feel it with them.

Empathy is a powerful tool both for understanding people around you, but also making them feel understood. When people feel understood, they can relax their defensive desire to fight for status or rightness, and genuinely open themselves to then understanding you.

Principles

1. Be genuinely interested in other people
2. Smile
3. Remember that a person's name is, to that person, the sweetest and most important sound in any language
4. Be a good listener. Encourage others to talk about themselves
5. Talk in terms of the other person's interest
6. Make the other person feel important and do it sincerely

Attitude: Selflessness

Selflessness is considering another person’s needs and desires before your own. Focusing on others means choosing to value their needs as if they were your own, which leads them to feel valued and ultimately to value you for the way you make them feel.
