When you buy something cheap, it is often likely to be expensive in the long-term; things that seem too good to be true usually are. When you are approached with an attractive deal, remember that nothing comes for free and there aren’t any no-strings-attached deals.

Do not keep any secrets in your career; people who keep parts of their lives secret usually are not being the people that they want to be; you will never find happiness unless you are the person that you want to be. Avoid jobs and professions that require you to keep a lot of secrets and hide your true identity. When you live a lie, you are the only person who ultimately gets hurt.

People owe their success to concentrating their energies and taking prompt action; they understand the importance of maintaining a positive attitude. People notice and gravitate towards those with a positive approach to their work, just as they notice – and do not respect - indifference and half-hearted work. A positive attitude, therefore, is your greatest asset.

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.

Everything you do is a form of preparation for your job interviews, as you are always under some form of scrutiny. The best employees can always spot other good employees, and you cannot “fake it”; merely doing a good job in your work is a form of interview preparation. Always put your all into your work, therefore, even if you do not have long-term plans to remain at your current employment. Switch jobs as infrequently as possible. The time to prepare for a job search is before you even realize that you need to do so.

Pursue your own dreams and become the person that you want to be, rather than what others might want. Living life according to the wishes of others is meaningless, and will bring you neither happiness nor success. Others do not understand your capabilities, goals, and interests as well as you do, hence their opinions should be your least concern. Have faith in your own potential greatness, and you will develop the confidence to act upon it and be the person that you really want to be, achieving true fulfillment.

In this article Harrison discusses how resisting change and not taking necessary and relevant action can be the biggest obstacles to a better career and better life. Resistance is something that prevents most people from ever changing. Resisting change can be highly damaging to your growth in your career and life. Instead of allowing your life to be controlled by external circumstances, choose to take action and bring about a change. Conduct a brutal self analysis if needed, to clear the blocks you have in your mind and to bring about change that is necessary. Most people give up. They do not persist. You need strategies and beliefs that will allow you to persist and persevere, so that you can change. The best strategy is to be focused, and this focus will help you overcome the resistance you face whenever you make an effort to begin changing.
