I love the stuff that Eric Barker pulls together because it’s always backed by research, and it’s beautifully cross-referenced. You can enter his site, barking the wrong tree and follow links till the cows come home!
How To Be Successful: 6 New Shortcuts Backed By Research is a great read that reminds you of things you already know and busts a few myths as well.
And this one: 10 things the most successful people do every day. I love the Mason Jar. What’s your favourite?
