It could all change in an instant! You receive a phone call from me and it’s your dream job. Actually, it doesn’t happen in an instant. You have or should be planning your long-term goals to determine what your dream job is. These goals help you differentiate between your dream job and all the other jobs that are of no interest to you. Don’t get persuaded by promises of a million dollar job in some place of no interest to you doing what’s not of interest to you.
It’s good to prepare for your dream job. Although you’re busy with your work, it’s always important to maintain professional contacts that might lead to your dream job. Also, each year just as you do your income taxes you should review your cv and add any accomplishments so that you don’t forget them at the moment that you need to present your cv.
