Maybe you could fill this list up with small things that you often take for granted, like being able to eat great food everyday and having a nice home to live in.
Or perhaps you might add in some more specific things that you're grateful have occurred in your life recently.
Make your list, say each item aloud and then make this a daily habit if you can.
You'll discover the more you express gratitude for even the smallest of things in your life, the better you'll feel, thus raising your overall positive energy and attracting more abundance into your life.
Doing this small exercise puts focus on what you DO have and not on what you DON'T have and makes you feel really great, so give it a go.
Just remember, gratitude is the BEST attitude!.
