You can do two things at once, but you can't focus effectively on two things at once. - Gary W. Keller

So, if you want to get the most out of your day, do your most important work — your ONE Thing — early, before your willpower is drawn down. Since your self-control will be sapped throughout the day, use it when it’s at full strength on what matters most.

I cannot believe that the purpose of life is to be happy. I think the purpose of life is to be useful, to be responsible, to be compassionate. It is, above all, to matter, to count, to stand for something, to have made some difference that you lived at all.

There can only be one most important thing. Many things may be important, but only one can be the most important.” — Ross Garber
