You'll never see a news item - outside of Vermont news shows, which can be incredibly quaint - that tells you that "a lot of things are actually going pretty well." So you have to do it yourself. The next time you hear about that earthquake in Chile, that plane crash in Malaysia, that terrorist attack in Sandy Hook, when you hear that the economy isn't recovering as well as you thought it would, when it seems as if the whole world is going to shit and people don't have any values anymore... just sit back, look at your own little life in your own little neck of the woods (or city block), and think "A lot of things are actually going pretty well."
And even if they're not, this is still a good thing to keep in mind. Even when your own life is dragging you down occasionally, when you reel from rejection and you have writers' block and your dog ate your homework and pooped it out on your new carpet and you feel a horrible cold coming on... when you just look closely enough, a lot of things are actually going pretty well.
You have a roof over your head, most likely a job to pay the bills, you have your health, your teeth, your limbs, your family, your friends. Even that it was sunny this morning falls under the "going pretty well" category, or the fact that you're still here drawing breath as we speak. Never take life for granted. Now say it out loud with me: "A lot of things are actually going pretty well."
