Have you met someone who just makes you feel good when you’re around them?
Be that person to other people. How? Listen to them intently, encourage them (with verbal and nonverbal cues) to keep talking, be interested, know when to add to the conversation/when to interrupt and when not to, smile, don’t be too eager/annoying, if they’re busy with something then leave them be. Have interests. Have things to talk about, but don’t always make it about you. Ask questions. Be approachable. Include others in your conversation. Be nice – not only to that person, but to everyone around you. Be a person of integrity. Be an expert in your field. Know your worth.
The more likeable you are, the further you are likely to go. “You can go fast alone, but you can go far together.” The more people enjoy your company, the more they will try to help you achieve your goals. Let them help you and you will go far.
