What we focus on is what we get.

Appreciate all the good things in your life.

This one is so easy!  The human brain has evolved in such a way that we tend to scan our world looking for negative things and possible dangers.  But you can retrain your brain to start looking for all the positive things that are going on in your world.  This is a habit that is guaranteed to make your ordinary life feel extraordinary.  As Shawn Achor writes in his book, The Happiness Advantage, the best way to retrain your brain is to write down three new things you are grateful for, every day. The best time to do this is first thing in the morning or last thing at night.  I do it at the same time I'm setting my intentions for the day.

Here are some of the things I've written:
     I'm grateful:

• my mother taught me how to sew.
• for the giant sunflower in Kristin's yard.
• I can read books for free on Overdrive.
• Susan gave me a good painting critique today.
• it stopped raining.
• for french fries.
• for my new pen.

It doesn't have to be anything big or momentous.  This habit will have a snowball effect, and you will find yourself gradually noticing positive things in your life all day long.  I highly recommend Shawn Achor's books.
