Getting Things Done® (GTD®) is a highly effective approach to productivity that was developed by David Allen.

It emphasizes the importance of developing a trusted system so that the mind can be freed to have ideas, rather than hold them.

It’s possible for a person to have an overwhelming number of things to do and still function productively with a clear head and a positive sense of relaxed control.
