T rue happiness is short lived. It is a flame that burns brighter than the sun but wavers all the while and eventually goes out. There is good news though, happiness is easily re-ignited. True happiness lives within us all. If you try to, you can see much of the world with the same joy and surprise every day.
Misery is the flip side of the same coin.
Only YOU can doom yourself to it. Bad luck, failure, criticism, embarrassment can all seem miserable if you let them. Revel in it if you must, that too can be strangely enjoyable. The only failure is in not trying. Remember embarrassment can be a great opportunity to laugh at your own pretensions.
