It is not easy to find happiness in hardship, pain and sorrow, and some must carry a heavier burden than others.
But happiness does neither come from others, who show more or less kindness or gratefulness for your help, your efforts or services; the joy comes rather from unexpected highlights and moments - or findings and amazing discoveries. Happiness comes from our own heart, from the little things we enjoy to see on our path, from activities we love (even if we can't do them often), from thoughts, from the books we read, from family and our close friends. We are always expected to do much - sometimes too much - but we cannot expect the others to make the same efforts, as every individual has different skills and performances. And happiness comes from achievements and performances, overcoming our fears, weaknesses, or handicaps, from our own progresses, and from those we could make happy, even if it was only for a moment. And last but not least, all the good laughs shared in good company - or among strangers, a bit like "singing in the rain".
