Interested in social media, podcasting, business books and business? It's hard to think of someone who can speak with more authority on all of those than Bruce Daisley, ex-European head of Twitter, host of the No.1 business podcast Eat, Sleep, Work, Repeat, author of The Joy of Work and all-round business guru. 

So it was a joy to talk to him about all of this, and particularly his new book, Fortitude, and why it's NOT called Resilience. Along the way we take in TikTok, Elon Musk, the tombstone aesthetic, and why the platform you build for your book is at least as important as the book itself. 

Listen, and be ready to take notes. 

'Strategy is effectively the map which takes you to your destination... tactics are the vehicles you're going to use to get there.'

Jenna Tiffany has worked with many businesses who mistook tactics for strategy. She decided the best way to help them - and many others - was to write a book. Because books, as her foreword writer Dan Barker points out, 'can literally perform magic', providing all the value of the most expensive course on earth, in a fraction of the time, at a fraction of the cost.

Students of finance don't typically expect to be grappling with theology and philosophy. But over a long career in Wall Street, Dr Kara Tan Bhala has collected many fascinating real-life stories that demonstrate just how central an understanding of ethics is for a career in finance.

She's also shown that it's possible to write about complex ideas in a clear and straightforward way, using stories rather than abstract theories. (Parable, as she points out, is simply an ancient name for case study.)

A fascinating topic, and an equally fascinating conversation with a groundbreaking woman. 

The internet is a funny old place. Most of us can't live (or certainly work) without it, and our online relationships and conversations are just as real and valuable as those we have offline. But we're complex beings with lots going on under the surface, and the internet is no different. 

Psychologist Ian MacRae is fascinated by the 'dark' side of online - the 'unconscious of the internet' - and how we can use a more nuanced understanding of that to better inform our online lives. 

He also has some wise words on how to go about pulling complex ideas and vast quantities of research into a readable book - even when it means creating a volume of untold stories as a byproduct...
