Think of negative speech as verbal pollution. And that's what I've been doing: visualizing insults and gossip as a dark cloud, maybe one with some sulfur dioxide. Once you've belched it out, you can't take it back. As grandma said, if you don't have anything nice to say, don't say anything at all. The interesting this is, the less often I vocalize my negative thoughts, the fewer negative thoughts I cook up in the first place.
I've started to look at life differently. When you're thanking God for every little you - every meal, every time you wake up, every time you take a sip of water - you can't help but be more thankful for life itself, for the unlikely and miraculous fact that you exist at all.

There's a very passionate pro-chewing movement on the Internet called Chewdiasm. They say that we should be chewing 50 to 100 times per mouthful, which is insane. I tried that. It takes like a day and a half to eat a sandwich. But their basic idea is right. If you chew, you'll eat slower and you will get more nutrients.
