In any given situation, you must consistently do 10% more than those around you; this is the essence of optimization, a vital tool for career success. Self-optimization changes everything, and is one of the best ways to improve in anything you do. Even seemingly minor changes can yield major results, so pay attention to the details.

Since the sun does not always shine forever, you must take a pragmatic approach towards your life and career; remember that good fortunes are never permanent. Do not take your job for granted, but instead watch the market and be aware of other potential jobs. Rather than guard against change, be prepared for it.

In this article, Harrison explains the importance of understanding the fact that you are not entitled to anything. One of the greatest blunders that people make is to believe that they are owed something and also that someone else is to be blamed for what happens to them. These beliefs are traps and allow others to take control of their lives. Harrison states that you need to hold the reigns of your own life, do what you want with it, make the most of what you are capable of and take responsibility of everything you do. The scepter should never, under any circumstance, be given to anyone else. Your achievements, life, and income should be the result of what you achieve and not others. The people who are the happiest, the most successful, and in control of their futures realize they are not entitled to anything.

Rather than committing to a career, many people switch jobs and take positions that require completely different skill sets; consequently, they never truly master their primary skills. While there is nothing wrong with changing careers, you must find something and devote yourself to it; many people have succeeded in relatively simple jobs, because they have committed to and mastered their craft. Develop a specialized interest, nurture it, and continually improve at it, and you will find the universe rewarding you.

In this article Harrison discusses the importance of showing up on time. When you do not show up on time people are let down and they get upset. Their confidence in you is eroded. Not showing up on time conveys that you do not respect others and their needs. You should never show up late for anything. When you show up on time you send the message that you respect others and their time. It also sends the message you take others’ needs as seriously as your own. Being on time sends the message you will play by the rules, do what is expected of you, and do your best to get along with others and look out for their needs. You always need to be on time.

The most successful people in the world have found new ways of expressing themselves professionally. To be continually successful, it is vital for you to reinvent yourself and find new, fresh approaches to the world. Settling into a single way of doing things is dangerous as it makes you predicable, and therefore easier to replicate and ultimately replace.

When I was an attorney, I stopped going out to lunch with other attorneys during the day. The reason was not that I was not hungry. Instead, I stopped going out to lunch because just about everyone I worked with would want to dedicate the lunch to a critique—whether it was critiquing our bosses, coworkers, or others. When these people were not being critiqued, the job itself was being critiqued. When the job was not being critiqued, the attorney’s home life was being critiqued.
