mastery...........................

     Self-discipline begins with the mastery of one's thoughts.  Without control over thoughts there can be no control over deeds!  Let us say, therefore, that self-discipline inspires one to think first and act afterward.  The usual procedure is just the reverse.  Most people act first and think afterward (if and when they think at all).

-Andrew Carnegie, as he answers questions from Napoleon Hill

hangs.......................

 

Everything hangs on one's thinking . . . a man is as unhappy as he has convinced himself he is.

-attributed to Seneca

wildly.............................

. . . humans are wildly optimistic when we estimate how much time is needed to complete cognitive efforts.

-Cal Newport,  Slow Productivity

Healthy thinking..................

No one wants to hear this right now because we’re living in scary times but things will get better eventually. They’re likely to get worse before they get better, potentially much worse, but I have faith in our human spirit to continue moving forward.

-Ben Carlson, as culled from here
