Various over used thoughts that I'm keen on:

Whatever comes, let it come,

what stays let stay,

what goes

let go. 

- Papaji

Will you come with me to the mountains? It will hurt at first, until your feet are hardened. Reality is harsh to the feet of shadows. But will you come?

- C.S. Lewis, The Great Divorce

It’s dark because you are trying too hard. Lightly child, lightly. Learn to do everything lightly. Yes, feel lightly even though you’re feeling deeply. Just lightly let things happen and lightly cope with them. I was so preposterously serious in those days…Lightly, lightly—it’s the best advice ever given me. So throw away your baggage and go forward. There are quicksands all about you, sucking at your feet, trying to suck you down into fear and self-pity and despair. That’s why you must walk so lightly. Lightly, my darling.

- Aldous Huxley
