Don't be afraid to give your best to what seemingly are small jobs. Every time you conquer one it makes you that much stronger. If you do the little jobs well, the big ones tend to take care of themselves.
Dale Carnegie
If you cat tends to think that you are a Kitty Treat, when he takes his next bite, just say "No!" (don't hit him) and walk away from him. Totally ignore him! Sounds easy, but it really works for most cats. Here is a good way to train your cat not to do something (getting on tables, etc.). Keep a spray bottle of water handy. When you see your cat doing something that he shouldn't be doing...squirt water at him in the face. They really hate that!
