Is it about the cycles or the circles??

Alright ....I have this theory that says that everything are always either a part of a cycle or a circle!

To support this theory consider a bi-cycle-it is firstly called a cycle but it actually runs on circles .Now the confusing begins when i try to classify it as a circle or a cycle. People who ride a bi-cycle go-into cycles of pedalling and stopping , so where does this fit ? the ambiguity in the answer seems to support my theory of cycles and circles.

Now think about it the Earth goes around in an almost circular path and does this over and over again which makes it a continuous cycle ,here the earth by itself is a circle.

My theory fits in may be even in our daily lives. Sleeping, eating , working ( possibly !!) and then going back to sleeping which is a process which may be is governed by clocks for the most part . Note the clock's hands go around in circles.

Thinking about it i could go on............
