"There is tremendous happiness in making others happy, despite our own situations."
"Shared grief is half the sorrow, but happiness when shared, is doubled."
I don't know who the author to the above quotes are but I find them very true. Sometimes, when we are sad, we are so drowned by our own sorrows. We get depressed, we can't think about anything else. Least of all, trying to make others happy.
However, there is a joy in making people happy. We should try to practise it. We should continue to try to make others happy despite our own situations. And hopefully, in time, our own troubles will cease.
