I manage an online community for people who are innovating in education.
I do A LOT of things in a given day... I manage the design and development (aka programming) of our website, I help my team run the community and plan outreach events, I'm responsible for budgets and getting additional funding, building the vision of what we're doing and making sure we're bringing it to life. I go to and speak at conferences. And email, I answer a lot of emails.

Be curious and be resilient. Curiosity: your interests will change, especially if you expose yourself to a lot of things. My career has gone in many different and interesting directions because I kept asking questions (of myself and others) and trying to find more information. Resilience: When something doesn't work out, give yourself time to mourn it, then pick yourself up, wipe your knees off and try something else. There are many opportunities out there, but you have to keep finding them.
