# Séance découverte with Thomas — VESPER

> Vingt minutes en visio pour regarder ensemble ce qui te gouverne en ce moment, et vérifier si l'accompagnement VESPER est fait pour toi. Tu repars avec le nom de ta boucle — pas avec le protocole, qui est le travail lui-même. Ce n'est ni une séance de travail, ni une consultation médicale ou psychologique.
