The 5 Second Rule: Transform your Life, Work, and Confidence with Everyday Courage
I was fortunate enough to see Mel Robbins present at a company event, and she was as inspiring as you may have already heard. While the premise of this book seems, on the face of it, laughably facile, there is a reason why this approach has achieved such rave reviews and plaudits.
The fundamental message here is that we tend to keep getting in our own way, being an obstacle to our success, often over things that are largely inconsequential. This is one tool you can use to help overcome fears and doubts, and it has been truly transformative for many people – I would highly recommend this as a good read, and suggest you put your skepticism on hold for the duration of the book.
