Have you been to Hubspot's annual INBOUND conference yet? If not, you're missing out on a lot of insightful and informative sessions and advice from industry pros about all things inbound, so ask me about registering for INBOUND 2016.
One of my favorite gems from INBOUND is Beth Dunn's BOLD "Fix Your Writing" talk. It's actually a few years old, but I refer to it over and over again to remind myself about the most important advice we can follow as online marketers: write every day, even if it's crap. Even the best and most influential writers turn out mediocre writing on some days and that's okay. The most important thing is that they write EVERY DAY. You can always refine it after you get the words down on paper or on your screen.
