Don’t wait until they tell you you are ready. The world might say you are not allowed to yet. I waited a long time in the world before I gave myself permission to fail. Please, Don’t even bother asking, don't bothering telling the world you are ready. Show it. Do it.
The deep, personal material of the latter half of your life is your children. You can write about your parents when they're gone, but your children are still going to be here, and you're going to want them to come and visit you in the nursing home.
Don't write your name on sand, waves will wash it away. Don't write your name in sky, wind may blow it away. Write your name in the hearts of people, that's where it will stay.
