I removed Facebook and Twitter from my phone. I still check them but not nearly as often now that they aren't my phone that's on my person nearly all the time.
I took all the games off my phone too except for Words With Friends. I like that one enough and it only takes a few minutes to play a word so I left it but all the rest of them have found themselves banished.
You'd be amazed (or maybe not) at the amount of time this has freed up. I should have done this a long time ago.
