“Happiness must happen, and the same holds for success: you have to let it happen by not caring about it.” – Viktor E. Frankl, neurologist and psychiatrist, and a Holocaust survivor

This brings the question; do you ever achieve happiness by pursuing it? 

“Happiness is not a goal; it is a by-product.” – Eleanor Roosevelt

It is in finding your purpose and being active towards that purpose where happiness will find you.  And if you don’t know your purpose, be active nonetheless.  Don’t wait for a bird to come and whisper to you what your purpose should be, or some extraordinary moment to provide you a clear purpose (although this one could happen).  The key here is to stay active and you will be sure to find your way!
