I'm very much in the creating space lately, which can be can be fun at times and deeply frustrating at others. Writing, in particular, is a lonely endeavor, and when you get to a certain level, sometimes it can be hard to find peers or even anyone who can relate. (More on this at a later date.)
Ira Glass made this wonderful video about why when you're doing creative work, there is always a gap in the beginning where you know what you're making isn't that great, but you should keep going. Eventually your taste and your talent will catch up. His point is that it's important not to give up when you know what you're doing doesn't match up to what you want it to be.
This is amazing advice, no matter what stage of your career you are in.
Also: before everyone gets into the armchair quarterbacking about the Superbowl ads (which were actually quite tame) they should read this piece about how using sex to sell things isn't always bad, and it has been going on for centuries. Even the Catholic church did it.
