They are supposed to be an easy way of making sure that you get things done.

Writing out a list of tasks is one of the worst ways of making sure you take care of your day's work, a leading time management expert has claimed

Kevin Kruse said that to-do lists are 'where important tasks go to die' and that they can make people more stressed out

His theory is based on interviews with over 200 high achievers - billionaires, Olympic athletes, straight-A students, and over 200 entrepreneurs—-including Mark Cuban, Kevin Harrington, James Altucher, John Lee Dumas, Pat Flynn, Grant Cardone, and Lewis Howes.
