So you have to do something for your life to change. If you don't change, or you don't put action towards changing your life, your life will never change. You can take yesterday and you can put it on to tomorrow, it'll be exactly the same.
And the better you become at focus, the more output that you're going to get for every single hour that you put in to whatever it is that you're working on.
Because most people, I'm this way too. Whenever I preach these things, these are all things that I practice in my own life because I am nowhere near perfect.
