In energy, as in life, the only constant is change.

Nobody understands when a woman makes a choice to marry and have children, in one way her life begins, but in another way, it stops. You build a life of details, and you just stop and stay steady, so that your children can move. And when they leave,they take your life of details with them. You are expected to move on again, but you don't remember what it was that moved you, because no one's asked you in so long.Not even yourself.

The only freedom which deserves the name is that of pursuing our own good in our way， so long as we do not attempt to deprive others of theirs or impede their efforts to obtain it.
