On the eve of his 36th birthday, bestselling author and journalist Mike Gayle picked up a pen and contemplated his life. In less than twenty-four hours he would be officially closer to 40 than to 30; his second child was due; his ten-year wedding anniversary imminent - despite his best efforts he had become an adult. Well, nearly. Gripped by a determination to sort out his life once and for all, Mike writes a To-do list of all the things he has meant to do but never quite got round to. Everything from empty kitchen of Chinese takeaway menus (467) to spend more time with parents because they won't always be around (12). It's a long list. There's a lot of stuff that needs doing. But unlike previous lists, made and long abandoned, Mike promises himself that this one will actually get DONE.
