Present continuous vs simple 2

Verbs that describe a state

The continuous is for actions that start and finish. Some verbs describe a state instead: something in your mind, your senses or your situation. These stay in the simple form, even when you mean right now.

Right now does not automatically mean the continuous. Ask whether the verb is an action or a state.
