Brother feeling the blessing is the contentment of the heart.
Abu Huraira reported: The Prophet, peace and blessings be upon him, said,
"Wealth is not in having many possessions. Rather, true wealth is the richness of the soul.”

To give you some examples. I myself look at my washing machine and i am SERIOUSLY FILLED WITH JOY!!. I am not kidding you. Even these words fall short for the joy and contentment i am having when looking at it. With that i feel the blessing Allah has given me.
Another example, having internet. I love knowledge and Allah given me internet i FEEL AS IF I AM THE MOST BLESSED PERSON ON EARTH for having it. Having tap water,..i mean DUDE..i HAVE TAP WATER
how can that not be a blessing? Every time if i am thirsty i just go in MY OWN HOUSE to the kitchen to drink some glass of water. Or Allah turned my heart and me worshiping Him..just go and praying how can i not be BLESSED of doing what i was made to do?
Ponder a bit more and ask yourself how come i am not happy with what i have? If it was up to Allah, Allah could have made me miserable and not have given me all those things and even MORE than i could count.
With your mouth you say you are grateful, but with your heart you are not. Because if you were, your eyes would be open and see all those blessings. You know the definition of the word "blessing" however you do not understand it. Understanding comes from the heart not the brain.
