‘This too must pass’
Not sure if they are exact words but I think it may have been Christ at some point during the Passion - it's a wile since I've been to church or read the New Testament...

couldn't resist a little search - if only life were that simple!
The origin of the saying "this too shall pass" appears to date back to a story told about King Solomon. It is said that the King, feeling blue, asked his advisors to find him a ring he had seen in a dream. "When I feel satisfied I’m afraid that it won’t last. And when I don’t, I am afraid my sorrow will go on forever. Find me the ring that will ease my suffering." Eventually an advisor met an old jeweler who carved into a simple gold band the Hebrew inscription "gam zeh ya’avor" – "this too shall pass." When the king received his ring and read the inscription his sorrows turned to joy and his joy to sorrows, and then both gave way to equanimity. More recently the saying has been popularized in the West by spiritual leaders imported from or inspired by the East, including Ram Dass, the Dali Lama and Tich Nhat Hanh.

Whoever said it they were wise words. I wish I could have just one original profound thought like that before I die, and then maybe future generations of bloggers would remember me

Now this is an improvement! You started with a positive (a good night's sleep) and ended with one (a beautiful morning). All you need to work on now is cutting out the gloomy stuff in between and you'll be sorted. "Accen-tuate the positive, elim-inate the negative". AND whatever you do, "Don't mess with Mr Inbetween"

I suspect all the truly wise things have already been said, probably several times over, things like: ‘Do unto others as you would have them do to you’, which seems like a pretty good basis for an ethical system to me. But it is up to us to learn from them and make them real in our own lives.
The one that really speaks to me is the First Noble Truth of Buddhism, which is ‘Suffering exists’. I believe it’s only by acknowledging this and truly taking it on board that we can accept that this is the way the world is and move forward. This seems to me far more positive and constructive than pretending that ‘all is for the best in this, the best of all possible worlds’. Actually, of course, this IS the best of all possible worlds, in that it is the ONLY world we have, and it is up to us to make it as good as it possibly can be – which we cannot do, either on an ethical or a personal level, by simply ignoring suffering and pretending it isn’t there.

"Enjoy it while you can" - I think we should strive for that - to enjoy the moment. There are many challenges in life, and it is up to us how we deal with them within the constraints of our own being. I think you're starting to get there.
