Of all the things you do to develop professionally, reading books is the most important, the most relevant.
You might read books about your line of work and about business and about how to be a better manager and those types of things.
But those aren't the books where you learn the most. Where you undergo personal growth. Where you experience the vast dynamism of the human condition. Where you empathize with the lived realities of people "not like you."
No, there aren't any "how-to" business books that teach you that stuff. That's not how it works. You learn that stuff by being interested in other people, other ideas, other cultures, other perspectives. . .on purpose.
You read books by and about people with whom you are not familiar on ideas and topics that you know little about so that you can expand your understanding of the world.
You won't see "read books" on any list of PD priorities. L&D leaders don't emphasize it. Companies don't value it. Leaders don't urge their people to read.
No, you have to want to do it on your own. You have to prioritize it. You have to emphasize it. You have to value it.
Or, you can keep making excuses why you don't read. And make everyone else suffer for it.
