From To-Do to To-Done. 2 letters different but a world apart.
To-Do List- A list of things you need to do. Typically a call list (calls you need to make but often don't get done. In business this may be a cold call or bad news call), a busy list (a list of things that make you feel like you are working hard) or insignificant things like chors. The To-Do list has no big thinking or aspirations.
To-Done List- This list is a list of things you have already done. It is a lifelong set of accomplishments, an ideology of how you live life. It sounds big, but it boils down to a few principles that guide you day in and day out. With maturity and a changing world view, the To-Done List evolves but is generally your ambition.
