Finding something interesting to do, and make healthy routines is the most essential for a happy life, and also have somebody to care for, and somebody who care for you!
Simple as that, still so difficult for many. Biatching about what is boring and who is happy or not, is just pure supidity. For some, just have a morning coffe, read the news at their table at that coffe shop in peace and quiet, see people passing by, is a good start for many. Why should anyone tell them, that is not good enough?
What you find interesting, fun and believe is a good life, can be totally boring and wrong for others. Give people some respect, earn respect back
