Let me make this very clear. Gratitude is the best attitude.
Saying thank you and showing appreciation can be done in many ways. But the most important thing is simply recognizing how fortunate we all are. The fact is, in this country, even our slums are better than the best of what many other countries in the world have to offer.
Our lack-based protective mind continuously looks for more (like a squirrel hording nuts for winter) and has a tendency to overlook and discount what we already do have. Consequently, unless we consistently remind ourselves to look for "what's right" in our lives, we often only see "what's wrong."
It takes courage to "want what we've got" and be grateful for what we already have. The ego will tell us that if we spend too much time appreciating what we have, we won't attempt to get "more" and disaster will eventually befall us. This is how the ego keeps us on the high-speed treadmill of "more". The fact is, however, that there is never an end to the chase. (We think it will end, but notice from your own experience that it never does!)
The universe has a rule that states, "If you don't appreciate what you've got then you won't get anymore." In short, if you don't appreciate one, you don't need two. Again, it's the old "use it (as in appreciate it fully) or lose it" deal. The power of appreciation particularly holds true when it comes to our finances. If you want more abundance, be grateful for and properly manage all the wealth you have now. Remember, what you focus on expands.
