If you are not living with a whole heart now, the end of the world poses no threat; your life is already gone. Life is only as valuable as our presence to enjoy it. To miss the beauty of the moment because you are preparing to protect yourself from the next one, is to trade a precious gem for a cheap trinket.
We attain freedom as we let go of whatever does not reflect our magnificence. A bird cannot fly high or far with a stone tied to its back. But release the impediment, and we are free to soar to unprecedented heights.
The point of life is not to be married or single - it is to be. We are human beings, or humans being. It does not matter so much what lifestyle we choose - it's what we make of the opportunities to grow, that counts.
