Ambiversion

Ambiversion-balance between introversion and extroversion; hence ambivert person having such balance.

Fear constricts

It entombs

Wraps in tentacles

And wrenches apart

Limb by trembling limb

Step into the light

To perform

For an audience

Never for yourself

Nerves

Adrenalin

Modesty

And Pride when your feet

Sink into the mud

And can still be moved
