I'm Ariel, and I'm here because I want to go on the journey of learning with others. Love and passion know no boundaries, and whether that’s in opening a new book or finding innovative ways to solve a math problem, the possibilities of learning are boundless. Yet in a world where we stigmatize making mistakes, we often feel isolated and alienated in our process of learning. I want to create a safe and inclusive environment where we can foster confidence and spark curiosity. I hold the quote "we don't make mistakes—we just have happy accidents" close to heart. And in these encouraging interactions, we find something more than joy; we find meaning. I'm grateful to be a part of a community of inspiration: a fearless place for us to build each other up.

Schedule

✋ ATTENDANCE POLICY

Please do not miss more than one session over the four weeks, as that will negatively affect your learning and may also take up a spot from another learner who could have attended every session.

If you reach two unexcused absences, your tutor may remove you from this series.

Note from Schoolhouse: This series has sessions with required attendance. If you need to miss a required session, submit an absence using the "Submit Excused Absence" button on the series page. Multiple unexcused absences may lead to a suspension of your Schoolhouse account.
