[vermilingua]

No, but "being lazy" is an action, which can be stopped. It's much harder to stop being lazy if you are being told it's a facet of your identity.

[Zak]

Lazy, here, is a state. It could be understood as a temporary state like being asleep or being hungry, or a facet of one's identity.

"Stop slacking" might be better; it unambiguously refers to current behavior that a person can change immediately.

It calls "being lazy" an intransitive verb

[thomastjeffery]

Lazy is an attribute.

"Being lazy" is a transient state.

That's the important distinction here.
