GTO-The One Thing -7 Habits

[BRANDY MEADE]

Hello, As someone who needs to get a handle on the chaos in their life, I was wondering which of these three programs you would recommend? I've heard really good things about Getting Things Done, The One Thing, and Steven Covey's 7 Habits. Hass anyone tried these programs and which do you recommend? Even becoming productive can be riddled with shiny object syndrome. ????Looking forward to your replies. Thank you.
