Another thing you can do for daily energizing and mindfulness is be pleasant. Say hello. Be perky. When you're at the grocery store, don't just sit on your cell phone at the cashier. Basically, you wouldn't even know if there was a human or an animal as your cashier. Look at them. Say hello. Smile. Be friendly. Be polite. It really changes our attitude for the day. Plus, it springsboards it back and forth because it brightens them up too, generally speaking. You might notice if you don't normally say hi to the cashier and you go ahead and you do it, that they might be pleasantly surprised and respond well to that.
