If you've held an iPhone you've experienced his influence.
His work includes focusing on the essential and removing the unessential. In a word, focus.
What are your essentials for the week?
If you're not already doing it, take a few moments on Sunday night or Monday morning and write down the top three things for the week that, if accomplished, would create the most impact for you professionally.
Then put them on your calendar.
Then do them!
Completing three significant initiatives, projects or action items will more your business and career forward faster than a week spent chasing administrative duties and trivia.
Focus and go!
