Bingo. Happiness is a talent that transcends conditions. Anyone talented at happiness will be happy whether they are rich, poor, or even missing limbs or paraplegic. Conversely, those talented at unhappiness will not only be unhappy no matter what, but they will drain the happiness from all those around them and in that find the only happiness of which they are capable.
“...they will drain the happiness from all those around them...”
I’ve known people of whom I’ve said: They drain the joy from everything.
