> Every photograph and video you take at a concert or other live event will probably be terrible. Just enjoy the moments, don’t feel pressured to document them.

I've changed my mind about this one because of a service called Timehop. Every day it grabs any photos, social media updates etc. from 1 year prior and stuffs them in an email (or push notification in the app). It's a great way to remember, and appreciate, what you've been doing and where you've been. A shitty little photo from a concert will take 15 seconds from "the moment" but give me that enjoyment back down the line, sometimes tenfold. (Since the additional marginal enjoyment of those 15 seconds is small, but the marginal enjoyment of reliving that experience a year later is much larger.)

Overall though I really liked the post.
