The most efficient way to live reasonably is every morning to make a plan of one's day and every night to examine the results obtained.
If I had to live my life again, I'd make the same mistakes, only sooner.
And I figured out that the reason I couldn't get through the day as well as I can now is because I had too many things on my mind, on my plate, you know, for one person to have. So I started to eliminate some of the things that were too heavy to carry and unnecessary.
