Cyclical

Everything cycles.

The Earth turns in a cycle, daily and annually.

The rain falls in cycles.

The tides ebb and flow in cycles.

Blood flows in cycles.

There is so much that is in a constant state of rising and falling. 

Coming and going.

Depression.

Contentment.

Energy.

It's all timed out, and we should know it by now.

It still throws us for a loop, though, when a number of the cycles sync up.

Then their effects get multiplied.

All you can do is wait it out.

Hang on for the ride.

Hope it evens out again.

It does even out again, right?
