Key takeaway is Confidence of Yourself and be Truthful when you speak
When one is confident of oneself, you learn to ignore all the other things that others downplay about you.
When you speak/converse truthfully, it is sincere, honest and you can easily answer any follow-up questions.
When one tries to talk big, any follow-up questions will be answered with a 'errr..." or stumbling answers. It's easy to call one out.
Don't use OTHER people's stories too often . eg.
"I know the feeling of being in a sports car because my fren drive one, very shiok. That day we took a long trip...."
"My fren's a SIA pilot, he says need to travel 3 weeks every month, very tiring, but the perks are good. His family also can travel with discount..."
Its your fren, NOT YOU who have the sports car or is a pilot. Repeat too many times in a single conversation, other party will think there is NOTHING interesting about YOU.
Be Yourself. That is who you want the other party to like you for
