People in general don't seem to realise how lucky they really are.
Like, they live in a first world country, have good health, a supportive family and still find stuff to complain about.
Where's the gratitude for what they have?
Ok, maybe they have something going on that I don't know about and that's leading them to be more negative than they usually would be. That said, counting your blessing is a good way to start thinking positively. No matter how bad someone's situation is, there is someone worse off, and as morbid as is sounds, if all attempts of being grateful have failed, why not kick start it by being happy you're not that worse off person?
But I find that it's the little things that seem to count most. Time spent with friends filled with laughter and far away from stress and worries, a stranger gesturing 'after you' through a doorway, a compliment given from the heart...
No matter what someone's situation is, there is always something to be grateful for, even if it's just a small moment in time.
