What's the recommended language to use to email this to my team?

If you missed it, here's what we recommend telling your team:

We all work so hard and sometimes when we get caught up in our own deadlines, meetings and to-do lists, we lose sight of what's most important around here: our team. Take a second to reflect on your week. We want to hear your highs, your lows, what's working, what's not working. Don't worry, Weekly Report is not some pointless piece of paperwork. We will read it. We will value it. And last, but not least, we will listen.
