The author moves on to talk about the unchanging fact that we cannot expect to make a difference to everybody without being a joke to others.
This is absolutely true, you can't impact the world, or even people around you without getting neglected or taken unserious by some , in the journey of life, don't expect everyone to clap for you.
They would always be people who are negligence about your impact, what's best is to ignore them and keep making progress.
Nice book, thanks for sharing.
