Cogs
We are all cogs in the machine of life. It doesn't mean a cog stays stationary. Cogs can plug in wherever they want. The difference is when a cog is cognizant of it's importance to the entire machine, it sees which other cogs rely on it to move the machine forward.
One cog doesn't make the machine. Life isn't about going it alone. It is about recognizing our unique way of movement and plugging in with others to move the machine positively.
