"You have so much to be thankful for..."
Gratitude is a way of life. It should be like jumping into a whirlpool of delight, lounging around, luxuriating in it -- AND NEVER GETTING OUT.
(I have a chef friend who is obsessed with bacon and she feels it's like jumping into a vat of bacon fat and just rolling around in it. What can I say? To each their own.)
No matter who you are, whatever circumstances you face; there is always, always something to be grateful for. This is not just some nice little positive thought for the day. Gratitude is necessary to survival and its opposite is insidious and odious. Entitlement is the father of self-pity, and this is what dwarfs the soul of man.
Gratitude is often misunderstood. Like it's some nice idea for a sunny day... Forget that -- IT IS THE SUN. It's what gives life to life! It's CRUCIAL. It's that grace of God that's so famously talked of, no, let's clarify: it's the experience of grace.
Accept all the good you can. Start by seeing it, recognizing it's value in your life, and then let the gratitude bubble up within as you lounge around in that warm and miraculous state of being that saints aspire to, would-be Buddhas cherish, and whose sanctified mystery poets both forlorn and hopeful exalt in odes and verse.
