Eric Keller and Jay Papassan write in their book, The One Thing, the surprisingly simple truth behind extraordinary results. Research supports that it takes an average of 66 days to develop a new habit. Focus on just one thing until it really becomes a habit then you will no longer require any willpower. Just imagine if you developed one new habit every 66 days, that would be five new habits a year. And what if you did that for five years, that could be 25 new habits? Do you think your life would be different? You can do it and I'm proof.
