I am a big believer in setting goals. As they say, if you don't know where you are going, any road will get you there. But I also believe that these goals should excite you. I understand the concept of SMART goals, but if you don't have a goal that excites you, you probably will not ultimately change your behavior.

Ultimately, if you want to break through a ceiling, you need to set goals that force you to re-evaluate how your are doing things now...so you can get where you want to be!
