Dusk and Dawn

I love dark nights and love sunny days,
Each is good in their own special ways.
Gloaming dusk follows dawn,
Day light goes, comes back on: 
From the sun's death and life, spirits raise.

Would you enjoy the sunshine if you banished clouds and the night? Would continual bliss be a curse?  We need both light and dark, night and day.  Happiness (or success) should not be the goal of life, rather it would should ensue when we lead significant lives, aligned to true purpose and meaning.  The last line, has a Tolkien like intent to speak to a Eucatastrophe

 “Don't aim at success. The more you aim at it and make it a target, the more you are going to miss it. For success, like happiness, cannot be pursued; it must ensue, and it only does so as the unintended side effect of one's personal dedication to a cause greater than oneself or as the by-product of one's surrender to a person other than oneself. Happiness must happen, and the same holds for success: you have to let it happen by not caring about it. I want you to listen to what your conscience commands you to do and go on to carry it out to the best of your knowledge. Then you will live to see that in the long-run—in the long-run, I say!—success will follow you precisely because you had forgotten to think about it” ~ Viktor E. Frankl, Man's Search for Meaning
