Some verbs cannot be used in the progressive tenses. They are called non-action verbs.
Non-action verbs indicate state, sense, desire, possession, or opinion. The most common
non-action verbs are:
be*
seem
appear*
(existence)

smell*
taste*
feel*
(senses)
like
want
prefer
love*
(desire)
have*
own
possess
(possession)
