In the book "Tipping Point," the author Malcolm Gladwell explains that a person can reach a tipping point in their lives when they have accumulated enough small and seemingly insignificant changes or events that eventually lead to a dramatic and significant transformation. This is supported by the poem on page 118, which discusses how small actions such as whispering and shaking hands can eventually lead to creating a revolution or causing a societal shift.
To reach a tipping point in life, it means having lots of small things that don't seem important add up and then suddenly causing a big change. The poem on page 118 shows that even small actions like whispering and shaking hands can lead to big things like a revolution or changing society.
