I don’t watch television. I don’t wake up late. And I don’t check email more often than I have to.
This means that I have 7 more hours in the day than everyone else has.
And in those 7 hours, if I spend 4 hours on productive work and the other 3 hours reading and noticing things, then I had a productive day.
Unfortunately, most people aren’t willing to give up these few things in order to work towards something better later on.
