This was one was derived directly from ‘The Secret’. It really is a virtue, not a value or anything like that (though I value it).
Those who are grateful, can stop striving. When you’re grateful, you can accept and live with what is in your life. If you’re grateful, you’re not annoyed. When you’re grateful, you love yourself.
The Law of Attraction goes a step further: gratitude is one of the conditions for spiritual (and financial) growth. After all – when you’re grateful, you’re not sending negative energy into the universe. And only those who send out positive energy will receive it [but after just reading ‘The Devil Wears Prada’ I’m not so optimistic].
Although I don’t personally see gratitude as a solution to all evil, I do agree that the only way to become happy is to be content with what you have in your life. But sometimes it does help to figure out solutions to problems you face, instead of forcing contentment.
