I often write and speak on workload management. But even I occasionally get overwhelmed by the sheer volume of requests and assignments. I’m in such a state right now.

In the last week I’ve attended board meetings for three different companies. Two were out of town. In addition, I have spoken publicly five times and am right in the middle of reviewing the copy-edited manuscript for my new book.

It’s easy to look at successful people and envy their situation. What you often don’t see is the pain they went through to get there. That certainly applies to me.

I didn’t eventually become a CEO because I made fewer mistakes than you. In fact, it’s probably just the opposite. I made more. In fact, I’ve been fired from three jobs in my career.

Each of these was a very painful experience. But these experiences also taught me important lessons that I probably could not have learned any other way.

Face it. You will eventually quit your job. It may be this year. It may be next. It may be ten years from now. But it’s inevitable. It’s only a matter of time. The only real question is how to do it in a way that doesn’t burn your bridges. You never know. You may want to come back. At the very least, you may need a reference.

Unfortunately, many people don’t always end their tenure at a company as well as they begin. The key, in my opinion, is to begin with the end in mind. As leaders, we should be intentional about everything we do—even quitting.

Recently, I had the opportunity to read an “advance readers copy” (ARC) of Seth Godin’s new book, Linchpin: Are You Indispensable? Admittedly, I am a fan. I have read most of Seth’s books. However, this is my favorite so far. In fact, I would go so far as to say this is the most important book I have read in the last year. In a minute, I will tell you how to get a free copy.

The list I posted yesterday was so popular, I thought I’d post a few more items from the original one. So by popular demand, here they are:

Thank God there is a filter in place between my brain and my mouth. If I said everything I thought, I would be in constant trouble.

Yesterday, while cleaning out my closet, I stumbled across an article I had saved. It is called “Things You’d Love to Say at Work But Can’t.” It had thirty-eight items. Here are the first ten:

Blame is the oldest game in town. It was invented by Adam who, after eating of the forbidden fruit, told God, “The woman whom You gave to be with me, she gave me of the tree, and I ate” (Genesis 3:12). In other words, it’s Eve’s fault. (And, by extension, God’s fault.)

Not much has changed since Adam’s day. Ask almost anyone why something bad happened and they will point to someone or something else. In my experience, it is exceedingly rare for people to stand up and take responsibility.

Most of us don’t spend enough time thinking. We are so busy doing that we have, I fear, almost forgotten how to think. Yet it is our thinking, more than any other single activity, that influences our outcomes.

The use of e-mail in corporate culture is pervasive. I rarely get letters any more. Even phone calls are uncommon. But I get scores of e-mail messages every day. Yet, I am continually surprised at how people often misuse this medium.

Tim Ferriss, author of The 4-Hour Workweek, provides some fascinating statistics about e-mail addiction and information overload on his Web site.
