This line of thinking comes from an understanding that change is constant and a belief that we can't write the history, because history is something that people in the past could write. But, what we need to look into more closely is that change happens all the time (the image below).
Start with the daily work that we are doing, see the small changes that are happening:
Updating a wallpaper on screen
An effort into reading more about the work we do
Watching a movie
These small tasks provide a small changes, which helps us take the further dependent tasks.
