It is a great book. It gave me permission to pursue different fields & hobbies without feeling guilt about abandoning them later. It suggested also various ways to pursue your interests. Some people are serial scanners, they get into one thing at a time. Ben franklin was like that.

Then there are some who are able to manage their schedules and pursue multiple interests at the same time.

There might be more types of scanners that I cannot recall but another type was scanners with one core interest and then various interests around it. This is what works for me, programming is my core interest and luckily pays well to let me pursue my other hobbies. Over years, I have had various hobbies and learned so many things. I feel I can find a common hobby/interest with almost anyone now.
