1. You're irreplaceable.
Okay, believing you're irreplaceable might make you feel great about yourself, but as soon as someone threatens to replace you in your position, you won't take it gracefully. Your pride might make you go apeshit or make you throw tantrums in public (yikes), as if feeling bad about losing your job isn't bad enough.
Fact: You aren't the only one who can do your job.
Fact: You aren't the only one who can do your job well.
The good side to this? You can take someone else's position.
2. You'll be rewarded for your outstanding performance.
Not consistently, because your boss might think you can still do better or not even be aware of all your big and small successes. It's good for you to continue keeping track, though. It'll be useful for your evaluations and salary negotiations.
3. Grad school will always make you more marketable.
It won't always put you at an advantage, especially if the field you're planning to get into doesn't need a graduate degree or has nothing to do with your master's or interest. (A college/university degree tells your employers you're competent and can work, while a master's degree tells them what you're really interested in.)
4. Lateral moves are useless.
They don't increase your salary, but that doesn't mean you've blown your chances of climbing the rungs. There are other ladders to the top, and being moved laterally gives you the chance of going to another top position in the future.
5. You'll be successful for sure if you put your career first.
Nope, not successful personal-wise or even career-wise. You don't always have to spend every minute of your waking life working. Experts believe that you also need to focus on yourself (and actually take vacations or breaks) so that you'll be more productive and happy at work, which has its promotional benefits for you. If you put your career first over everything else (by default) burnout is just waiting to happen to you.
6. Your career depends on your major in college.
That only applies to a career path that takes years and years of prep, like becoming a doctor, a lawyer, or a physicist. But otherwise you can be in the corporate world with a liberal arts degree or be a journalist with a music degree.
7. Do what you're passionate about and the money will follow.
This might be one of the hardest to swallow, because we've been told in our younger years that this'll happen. Unfortunately the real world doesn't work that way. Certain passions, like writing poems, don't yield enough capital for all the people who pursue it. It's only the lucky ones (the minority) who make a lot of money—but not always without being contested since they're not the best in their field.
A good alternative is to find a job you're okay with, and do what you love on the side.
8. Your job is all about what fulfills you and makes you happy; forget the money.
How you look at your job is how you look at it. If your priority is to earn a lot of money for personal or philanthropic reasons, then let that be your goal. It's very narrow-minded (bordering on bourgeois) to think that a job is all about fulfillment that money doesn't matter anymore. Fact is, money matters; it just differs in degrees to people, like if they need and/or want it. If it matters sooo much to you, then make the necessary decisions. (Just don't steal or be corrupt because hello, that's evil.)
