One success story could be when someone actively listened to others' problems and offered genuine support, which made them build strong friendships and gain influence.
There's a story of an entrepreneur who networked effectively by being friendly and helpful. As a result, they gained many business partners and were able to influence the decisions of their peers in the industry.
For example, a person who always showed kindness and respect to everyone they met ended up having a wide circle of friends and being able to convince others easily. This is a great example of winning friends and influencing people successfully.
