I think there is a difference between not having expectations and borrowing trouble. If you literally look for everything to go wrong, it will, and focusing on the negative makes you find it everywhere and not see the positive.

My view is that I am exceptionally lucky to be alive and physically embodied. On top of that I am not even in constant pain. Can see and hear and feel, can taste and read and dance. I feel true gratitude for being able to experience anything at all, to have a body and a mind. I’m not sure it’s optimistic at all, but I am happy.
