@kevinwong: I will suggest according to my point of view.
Becoming a mobile agent: for me MAC is best one and highly recommended due to their stable OS of course. For phone you can have Lenovo K6 for camera go for GoPRO.
Becoming healthy and lean: Drink a lot of water, when i say that atleast 30 glass, go for green vegetables., boiled stuff as well make sure you have enough protein.
Becoming more effective in staying connected, but having more off my time and attention offline: Give atlest 5 mins per hour, set and alarm or a reminder per hour.
Hopefully these will help you, what you are working on ;)
