Holding on to a career advice that was given decades ago will hurt your chances of success. That advice was given in consideration of the existing conditions then. Today, our world is vastly different from what existed in the last 20 or even just 10 years ago.

Here are some pieces of career advice that you should definitely ignore.

1. Your resume should be just one page

How can you enumerate all your educational qualifications, extensive experience and other extra-curricular activities in just one short page? To do that, you have to filter out what you think are the unimportant items in your adult life. If you do that, you might leave out something that may be of interest to a prospective employer.

Therefore, include every essential thing in your education, training, experience and so forth, making sure, though, that your resume does not become a short little book.

2. Follow your passion

This is another piece of career advice that is very popular ages ago. It seems pretty wise, but the better place for it is the waste bin. Let me explain.

If you follow this adage, you might be led into a deep rabbit hole where you can't easily get out of, and which might not give you stability and fulfillment.

You have to assess what the world is buying right now. Sure, you're good at painting realistic panoramic views, but is there anyone buying? That's only an example, of course, but I hope you see the drift.

3. All your related jobs since you graduated from college must be included in your resume.

Consider this career advice in conjunction with advice number one. You should understand that your resume is your sales letter to a prospective buyer - a potential employer.

Therefore, assess your job experiences in relation to the target company, and then craft a specific resume to hook up that 'big fish.' In other words, you cannot just pass up one single type of resume for all the companies you are applying for.
