Listened as an audiobook. 

Good:

 Simple tips, such as :
 Ask tough questions.
 Focus on details, even small ones.
 Learn from mistakes.
 See hard times as opportunities for growth.
 Teaching helps you learn.

Bad Parts

 Excessive boasting (Not very British, if I may say so)
 Jumbled narrative
 Broad topics, but doesn't look deeply at any of them. 
 The content often jumps around.

Who Should Read It?

 Best For:
 People looking for an easy read with personal development insights.
 Rubbish for :
 Readers expecting concrete business advice.

In Short

An interesting read that offers personal development tips but falls short as a business guide. It's best suited for people who want self-improvement stories and are prepared to sift through some terrible writing to find the gems.

The audio was great, clear and easy to follow. It was a nice motivational listen on my drives into work.
