Innovation can create a more sustainable world. I will spend 30 minutes learning about new materials, technologies, ideas, or practices that help solve environmental challenges and improve our planet's future.

I will approach my visit with respect by researching its importance and guidelines beforehand, reflecting on how we can preserve these spaces for future generations.
Staying connected strengthens relationships and boosts well-being. Each day, I will reach out to 1 friends or colleagues to check in, have a meaningful conversation, or offer support.
