You are what you read! Just some of my favourite books which I would encourage you to read.
A small hack you can use: Don’t want to read the book? Visit YouTube and enter the name of the author. You can find some speaking events with the author and this will give you a good idea about the books they write and the ideas they have. E.g. Before seeing if you should read “On Becoming a Leader” by Warren Bennis – go to YouTube and type “Warren Bennis” and hear him speak about leadership at an event.
