It's certainly part of it. Here's a terza rima sonnet I posted two years ago:

Write to merge my soul and my consciousness

Write for expansion of my higher self

so selves integrate as one consciousness

Write so my demons remain on the shelf

and even when they escape their cages

I learn and know how to protect ourself

Write to express and temper my rages

Else my anger can turn to resentment

Progress not perfection comes in stages

Write to increase base-level contentment

Not for insane pursuit of happiness

and to avoid depths of self-contemptment

Write to share feelings and avoid numbness

and return to state of inner youngness
