Animals have no doubts because they have no minds (ego). A cat does what a cat is supposed to do without any judgments or considerations. It chases a mouse and if unsuccessful it pursues another option to feed itself. Have you ever seen a cat, or any other animal for that matter, to put its paw on its head saying "you're such a bad cat because you couldn't even catch a mouse?"
Start the New Year on the right track. Make a decision to be the master of your thoughts. What you think has enormous power over what you say to yourself and others, and what will eventually manifest: good, bad, or ugly! The real trick is to harmonize your thoughts, words, and actions. This harmony will put you in the driver’s seat of your life.
