Help others. This is the old and ever new way. As Maeterlinck says:
“_Before we can bring happiness to others, we must first be happy
ourselves. Nor will happiness abide within us unless we confer it on
others. If there be a smile upon our lips, those around us will soon
smile too; and our happiness will become the truer and deeper as we see
that these others are happy._”
Therefore, keep happy by helping others. We can help others by our
thoughts--by wishing them to be well and happy and successful, or by
imagining them to be well and happy and successful. We can help them by
all our expressions--our words, our looks, our acts--and by our very
abstinence from non-happiness.
