Just like others have said, I also greet the morning with thanks to have woken up to a wonderful new day.
It's almost second nature to me now.

I once spent just over 3 months in a buddhist temple in the mountains of Japan.
Each morning we would wake up at 4am and chant our mantra which meant something like, Thanks I am alive and have a precious life. I promise not to waste my life. I promise to use my special energies to develop myself
and to let my heart reach out to others. I want to achieve enlightenment that brings benefit for all.
I want to be calm and kind in action and thought. I will not get angry or have bad thoughts about others. I want to help other beings as much as I can do.

Not that I'm a Buddhist. But it was a great experience. I learnt a lot of good stuff about myself
