Another point from the presentation of Dr. Gail Davies which I agreed
100%. It is to easier to start a new difficult task with a small and realistic step. She gave an example that people training for marathon usually start slowly with a much shorter distance than 26.2 miles and build it up gradually. One main reason is to avoid frustration and giving up immediately if we don’t build it up. I think it is logical and sensible as mentioned in my book (Section “Invest the time to work on the basics” p.34-35).
