1) To KNOW things - study; find out things; practice things; get skillful and knowledgeable.
2) To BE THANKFUL - everything is a present; focus on the best things; I know about the bad and I see the good.
3) To BE HAPPY - meet the world with joy; I lay for two years on the frozen bare dirt with my son and I laughed - what five and a half year old would not laugh under those circumstances?
How hard is my life? I can rise above my petty notions as she rose above monumental hardships - because she found what was good in it and knew that "people complain. Complaining changes nothing."
"I know about the bad, and I see the good."
