The 21 Biggest Career Mistakes You Can Make

If someone in your office is struggling with their task, you should lend a hand. Sure, it may be extra work, but you'll be seen as a hero in the office.

It may be tempting to go after more money at the beginning of your career, but experience is key. Take jobs based on how much you'll learn and you'll make more in the long run.

Not everyone has to follow the rags-to-riches path. Starting at the bottom may delay your progression up the food chain. Shoot for better.

It's important to network inside your company, but it's even more important to establish relationships with people from different companies so you learn about different corporate cultures.

You need to be flexible at the beginning of your career when it comes to moving. Don't tie yourself down with a house and mortgage as this will make it much harder to transfer to a different city at a moment's notice.

Always know your goals and keep looking ahead. If you think you're on the wrong path, make a course adjustment now – don't wait.

Don't fall into the trap of acting entitled. This definitely won't endear you to your co-workers or boss.

If you're in the wrong job, start making plans to find the right one. Don't waste precious years waiting for something better to come along.

Don't waste time comparing yourself to others. If someone is doing better than you, learn from what they're doing. But don't let it bring you down.

There are times that we have to go above and beyond at work. Don't act like working hard isn't part of your job. Even if it costs you some time, it shows that you're a team player.

Taking on extra work is good, but don't take on too much. You want to make sure you can do it properly and not let it interfere with your regular duties.

If you're looking to jump ship, make sure you do your due diligence. It can be a mistake to leave a good track record for a job that won't help you progress.

One way to slow your career progression down is by not preparing for a job interview. Don't waste their time or yours.

Be nice to your fellow employees, even if it's hard. Getting a reputation as a jerk can come back to haunt you.

It's your career, don't let anyone push you in a direction you don't want to go. What might be right for your employer isn't necessarily right for you.

Make sure you always look professional – it says you care about your appearance and the company's.

Don't talk about private company business on social media. Ever.

It goes without saying that burning bridges, especially early in your career, is a big mistake. Always be a professional.

Your social media profiles should present you in a good light. Make sure you hide unflattering images and comments. This is especially important before applying for a new job.

The harder you work now, the more it'll pay off later.

Work hard, yes. But take time to enjoy life. Don't regret not doing things when you were young – you may not get the chance again.
