When you are a magnetic person, you are a master in the art of listening.
You don’t want fake interest; you want to understand what people ask you for indeed.
So you listen, and when it is your turn to speak, instead of sharing some narcissistic bullsh*t example from your life, you use the opportunity to ask more questions to have a clear vision of the thing or problem that person is saying to you.
Friendship is like gardening; you need to water the field to see the plants grow. And you do that with time and active listening.
If people can feel your genuine interest in their lives, you’ll be irreplaceable as a reliable person and friend.
