Attitude is one of the most contagious things I have encountered. It is so easy to catch a case of the grumps. Once contracted they can be difficult to get rid of. I've tried many traditional remedies including chocolate, coffee and losing myself in a book, all with varying amounts of success. The odd thing about attitude is that it gives us a choice. We can catch it or we can shake our heads and choose for ourselves what tone we want for our day. Chocolate, coffee and a good book may still be in order as maintaining an attitude of choice can be somewhat tricky.
I challenge you to choose your attitude for yourself and make it work for you, not the other way around.
