If you are like most people, you will be happiest doing the things you do best. So think of this step as a quest for self-fulfillment rather than as a thankless chore necessary for putting bullet points on a new résumé.
Write down the three things you like best about your current job. Then write down the three biggest successes you have had in the past several years. What are the skills you used to generate that success? Finally, write down the three things you think you could do or would like to do. Do you have the skills to realistically pursue your wishes? Which skills should you improve for your dream job?
Use this improved understanding of your own drives and capabilities to steer your search for the next step in your career. And put them on your résumé: that way you'll get the job you were put on this blue earth to do.
