Everyone has a sense of humor. If you don't laugh at jokes, you probably laugh at opinions.
A Manifesto for Introverts 1. There's a word for 'people who are in their heads too much': thinkers. 2. Solitude is a catalyst for innovation. 3. The next generation of quiet kids can and must be raised to know their own strengths. 4. Sometimes it helps to be a pretend extrovert. There will always be time to be quiet later. 5. But in the long run, staying true to your temperament is key to finding work you love and work that matters. 6. One genuine new relationship is worth a fistful of business cards. 7. It's OK to cross the street to avoid making small talk. 8. 'Quiet leadership' is not an oxymoron. 9. Love is essential; gregariousness is optional. 10. 'In a gentle way, you can shake the world.' -Mahatma Gandhi
Senses of humor define people, as factions, deeper rooted than religious or political opinions. When carrying out everyday tasks, opinions are rather easy to set aside, but those whom a person shares a sense of humor with are his closest friends. They are always there to make the biggest influence.
