Yep. If you are one of them, you would obviously know it, wouldn’t you?
I call GRATITUDE the noblest of all virtues because it encompasses all other virtues. Carrying this highest virtue all the time can act as a ring of protection around you. People might have helped you, monetarily, in finding a job, a life partner, or something else you wished for, but the one who has given you their time, has given you what is most precious to them – a part, however small or big, of their own life. Remember this always.
