Below are my own Cstan98 study notes. Not mean to replace actual course.
This world is about interactions with People. No man is an island.
Finish interactions when other parties are most interested. So that S/He eagerly wants next interaction.
Your hands/legs should not be crossed (barrier defensive). Your hand should not be supporting your chin/face (bored). And ...
Always have eyes contact in social interactions. Eye contact change shy person life. Last time. The me Cstan98 is very shy. Always look down on the floor = no friend. Until me knows importance of eyes contact. After maintaining eyes contact with strangers. Begin to have more friends. Then more conversations. Keep on having more good friends. Finally. It means getting Wife.
(00) Need to be aware of your face expressions.
(01) Are you smiling when you are saying sad things?
(02) Do you have blank face?
(03) Do you smiles often?
(04) Sad face when saying happy things?
(05) Your face needs to portrait angry/disgusted/happy/sad/... faces when needed.
Be Top Gun = 50% Iceman (ice cool no mistake) + 50% Maverick (unpredictable when needed).
Central Church Christian. How to be likeable in workplace = humble + child-like.
Nod your head? To continue/push more interactions.
If you seldom smile. You need to learn to smile a lots. May need to practice in front of Apple MacBook Photo Booth.
Your tone of voice should be pleasant. And not harsh. Or too loud/soft. Need to be just nice.
Practices make perfect.
