Using a to do list has really helped me to improve my effectiveness and productivity. It works best when I write the day's list, the previous evening and put the most important tasks at the top of the list. Normally I only spend five or ten minutes every evening writing my list. Recently I've been thinking that it could be very productive to spend a lot more time on writing a To Do list, perhaps from thirty minutes to an hour. If you work long hours during the day, could you benefit from spending an hour of that time preparing for the next day's work and really taking the time to plan your day? Would this be over planning or would it be a helpful step towards your success? If you write a To Do list, how long does it take you? Would you benefit from spending more time on it?
