One of our new members has one of my favourites as his (her?) profile picture (thanks NASH256!)
"A smooth sea never made a skilled sailor"
I also like
"the salts of life make the fruits taste sweeter"
oh and edited to add, my profile picture says:
"the most important thing I've discovered is that I can no longer waste time doing things I don't want to do"
It's from the film The Great Beauty, and comes from the simple moment when he doesn't feel like looking at a lover's "selfies" but I think of it in regards to my drinking. I just can't waste any more time doing that, I don't want to.
