Social media allows me to pick my times for social interaction.

I would consider...Google Plus a push technology. It's closer to Twitter than to Facebook.

Eat like a bird, poop like an elephant.

Twitter, Facebook, Google + are the trifecta of marketing for authors (and bloggers).

If you want to make a good first impression, smile at people. What does it cost to smile? Nothing. What does it cost not to smile? Everything, if not smiling prevents you from enchanting people.

The hard part is implementing the decision, not making it.

Simple and to the point is always the best way to get your point across.
