I've tried every to-do product out there - none worked for me. The best method I've found is to actually schedule time in my calendar to work on different projects. I find if I don't block out time to actually work on them, they don't get done. Does anyone know of a to-do list manager that works this way? I ask because while I like this method, it is difficult to see all your to-dos or deal with a to-do that has multiple steps.
