Habitual aspects of the verb to be.

To express habituality in the past we use used to be, because was/were dont serve that purpose.

But in present, am/is/are do.

For example: I'm tired rn (this is how I feel at the moment).

I am at school when my favorite show comes on TV so I'm never able to watch it. (Here being at school is a habitual action/general truth. Not like he's actually at school atm)

Am I right?

This is how I interpret it.

Because in my native language.

We have two separate forms of to be

To express a habitual and non habitual action. So when I learned about this at first place. It blew my head.
