Before thinking about how to be grateful, you need to evaluate and understand how grateful you are now.

This is easy enough to understand. Ungrateful people are often offended by life and are constantly upset about what happens to them, they are rarely satisfied with themselves and often complain about injustice.

Only observant people know how to say "thank you".
To begin with, we have life, you can be grateful to everything until the end of days just for this.
Because everyone around us has life, it never ceases to be the greatest gift.

Each person has so many opportunities to reveal his potential, an infinity of different activities, people, circumstances, feelings. How can you be indifferent to the fact that you have been given life, how can you not be grateful for this?
The world around us is so multifaceted, eternity is not enough to study and understand it. You just need to notice the miracles around.
