I’ve just finished writing a new book on empathy, due out early next year, provisionally titled Empathy: A Handbook for Revolution. In my effort to get the manuscript in on time, I’ve been neglecting answering emails and dealing with bills, and my study is piled with bits of paper that I’ve been meaning to file for months. I just came across one of those bits of paper that I’d completely forgotten about. It’s a list of 17 ideas to help you seize the day, which I prepared for a School of Life project a few years ago called Carpe Diem Daily. The project (which is now over) involved creating a website that offered participants a simple daily task where they were invited to snap a photo, make a short video or write a few lines of text that could be shared online with others. So here are the tasks I contributed (along with people like the guerrilla gardener Richard Reynolds and the slow-culture writer Carl Honoré). You might consider trying out a few of them for yourself and posting the results in the Comments section of this blogpost.
