     I'm one of those people who are terrible at saying no. I spend too much of my time doing things I'd

rather not be. I get things done, but it's not always the best I can do, or the best way I can spend my time.

That's why my newest goal, both as a professional and a person, is to be a quitter.

     Being a quitter isn't being someone who gives up, who doesn't see important things through to the end.

I want to quit doing things that I'm asked to do. for no other reason than I'm asked to do it. I want to be

able to quit something in mid-stream, because I realize there's nothing good coming from it.

     A friend of mine once told me that"I knew I was an adult when I could stop reading a book, even after

getting 500 pages into it."Strange though it sounds,we all intend to do this. We get involved in something,

realize we don't want to be a part of it, but just keep doing it.

     What I advise is to quit as often as possible. If you're stuck doing something, and don't really want to

do it anymore, step back for a second. Ask if you really have to do this, and what value is being produced

from your doing it. Don't think about the time you've put into it or how much it's taken over your life. If

you don't want to do it,and don't have to do it, don't do it.

     By quitting these things, you'll free up time to do things that actually do create value, for yourself and

for others.You'11 be able to begin to put your time and effort into the things you'd actually like to do.

     Let's learn how to say"no" at the beginning. or in the middle. Let's see to it that we're spending our time

creating value, rather than worsening our losses. Let's be quitters together.
