An influential Guru in India always reminds his flock: When you wake up, be grateful that another day is waiting for you.
In the Yogic teaching, along with any philosophical teachings over 2000 years old, being grateful is accorded a status in the hierarchy for self-contentment.
When you wake up, I do not remember who it was who told me, make up a grateful list of five people. In the beginning you are going to thank the usual souls in your emotional circuit, husbands, wives, parents etc. As you continue this routine, people whom you owe a word of gratitude and have not thought about them in decades begin to appear on the list. And that would bring a smile to your face.
During these difficult times, if someone says each day is similar to the other, it is their inability or lack of habit of the person to say thank you for a new day and that they have not learned to be grateful for the things that enter their day, each new day.
As my UmonHon Indian teacher told me: Be grateful for what you have, not be ungrateful for things you do not have.
