Since it was released years ago, I've been a big fan of 'The Secret'. Some call it the power of positive thinking, some call it the law of attraction. Either way, it's all about drawing more positivity into your life, by thinking more positively.

Thoughts become things.

Rhonda Byrne is the author of 'The Secret', and she once said, "To improve any day immediately, say and feel, 'Thank you,' seven times in a row."

TD Bank in Canada took a simple "thank you" and turned it into a viral phenomenon. You'll see why, about halfway through, this video has gotten well over 3.5 million views.

May the joy be with you.
