When the sun comes up in the morning, you know this is a part of a cycle.  When the sun sets in the evening, you know the cycle will continue.  You do not wonder when the sun disappears at the end of the day if it will rise again.  You count on it and act accordingly.

Whatever else is going on, there are certain cycles that play out in your life, over and over and over again.  Look for the other cycles in your life.  Are there cycles in love? prosperity? friendships?

When it gets dark in the evenings you adapt to that stage of the suns cycle.  You have learned to accept and adapt to periods of darkness.  You behave differently then you might when the sun is bright.

Witness the other cycles in your life and take note of how you adapt to darkness vs. light.

Try not to fret their passage.  Things will always change and change and then change again.  You can fight it, fear it, dread it or hate it or you can smile, accept it, embrace it and adapt, with the eager anticipation of waiting for the beauty of the next sunrise, knowing that things will change again.  The choice is yours.
