Never misunderstand seriousness for sincerity. Sincerity is very playful, never serious. It is true, authentic, but never serious. Sincerity does not have a long face, it is bubbling with joy, radiating with an inner joyousness.
Seriousness has become almost part of our bones and blood. You will have to make some effort to get rid of seriousness, and you will have to be on the lookout — wherever you can find something humorous happening, don’t miss the opportunity.
