Knowing about gratitude is great. But applying the knowledge is paramount. Let's look at some action steps you can take today for your particular situation. Take out your pen and paper and do the exercise.
Action Step #1 - What can I be grateful for today?
You may find that you start off with just one thing and then it begins to expand. Keep going. Don't hesitate to get more paper if you run out of space. That's a very good sign. Don't sweat it though if you only have a few to start with. That's okay too.
Action Step #2 - What troublesome situation are you facing?
Look at the troublesome situation right now and ask,
1) What's the good in this?
2) What can I be thankful for?
Action Step #3 - Be thankful all day
Focus on the one or more things that you can be thankful for all day today and continue to express your gratitude. You may say something like, "I may not have my dream car right now, but I am thankful that I can still get to my destination and remain warm in the car that I have now. All is well."
