Inertia

Inertia is a physics concept that basically means things keep moving in the same direction and at the same speed. On, and on, and on.  They don't stop. They don't slow down. They don't change direction. I've been feeling like my world has been doing the same thing. I think this is what normal people, meaning non-science nerds, call being stuck in a rut.
In school world we are between quarters, finishing up one with another one just getting started.  One day ends and the other begins. And so the cycle continues. Inertia.
The thing about inertia, though, is that it can be changed when acted on by a force.  This force can cause our object to slow down and eventually stop or it can change the object's direction.
I would say that the same is true for our own lives (beyond the physics and science realm that is). We can keep on keeping on; plodding along an endless trail. Or we can introduce a force and change our direction.
Perseverance is an admirable quality but I think it needs to be spiced up from time to time by doing something different. Force yourself to try something different.  Force yourself to break out of the routine.  Force yourself into a new direction.
