Do you love your job? Make sure you don't blow it and lose your career with thoughtless little habits that you are comfortably beginning to get accustomed to. Keep track of the little things — like getting to the office on time and being kind to your co-workers. Business Insider  shows us that there are 15 ways to slowly ruin your career without even knowing it. Check out which habits to avoid below.
There are big mistakes that can instantly ruin your reputation at work or even get you fired. But more commonly, it's the gradual accumulation of smaller offenses that keeps employees from getting ahead in their careers.
Bad habits, such as giving curt responses to emails or keeping to yourself all day, could be hurting your reputation — whether you realize it or not.
Here are 15 bad behaviors that will slowly erode your credibility and cost you in the end.
1. You don't adapt to the company culture.
Every workplace operates under its own set of social customs. Not making an effort to assimilate into this culture can make you seem disapproving or judgmental . This holier-than-thou attitude is alienating to co-workers and makes it seem like you don't care about forming positive relationships in the office.
2. You make excuses.
Not taking responsibility for your mistakes and failures will catch up with you. Waiting until the day a project is due to explain why you're behind, for example, tells your boss that you can't manage your time well .
3. You do the bare minimum.
Even if you always meet deadlines and consistently turn in quality work, doing only the bare minimum  makes you seem complacent. On the other hand, looking for opportunities instead of waiting for them to fall into your lap shows your boss that you're driven and care about your future at the company.
4. You don't follow through.
When you fail to do what you say you're going to do, from restocking the printer to copy editing your neighbor's report, you garner a reputation for being unreliable. Keeping your word shows that you're accountable and can be trusted with more responsibilities  when it comes time to be considered for a promotion.
5. You dress like a slob.
Once you're settled into a position, it can be easy to let your appearance fall by the wayside. However, failing to look put-together undermines your credibility and authority  and may make you seem like you don't care. Remember the age-old saying: Dress for the job you want.
6. You're a pessimist.
If you're habitually sporting a bad attitude, you become a nuisance to your boss  and can drag down your team. Constantly whining and complaining won't make you pleasant to be around, and certainly won't entice your boss to keep you around for long.
7. You ignore co-workers.
Forming friendships with your colleagues is just as important as cultivating relationships with higher-ups . Strive to be known and well-liked, so that co-workers want to share valuable information with you and help you when you need it.
8. You're defensive.
Your boss doesn't expect you to be perfect, but getting defensive when receiving negative feedback makes you look unprofessional . If you're unwilling to listen to constructive criticism, it tells your boss that you're unlikely to push yourself to improve.
9. You procrastinate.
Putting off projects until the last minute not only puts stress on you, it hinders the progress of every other person relying on your portion of the work. If something goes wrong, you'll likely be the first one blamed.
10. You write brusque emails.
No matter how friendly you are in person, terse language can easily be misconstrued in an email. Even if it's unintentional, rude emails immediately sour your reputation around the office  and keep others from wanting to interact with you.
11. You don't make meaningful contributions.
Saying something in a meeting just for the sake of speaking doesn't add anything productive . Instead, prepare ahead of time, and remember quality over quantity when sharing ideas.
12. You're always late.
Frequent tardiness signifies to co-workers that something else is more important to you and that you don't value their time. It paints you as disrespectful and uncaring, making people wary of trusting you. No matter what it takes , always find a way to be punctual.
13. You never stop talking.
Yes, it's great to get to know your co-workers, but if you're constantly socializing, it prevents everyone around you from getting their work done. Keep the chatter to your lunch hour and breaks to avoid annoying others and becoming the person no one wants to work with .
14. You ignore emails.
Failing to answer emails in a reasonable timeframe not only frustrates those who need responses from you, it signifies to colleagues that they aren't worth your time , can cause you to miss deadlines, and generally paints you as unprofessional. Although answering each one as soon as it's received is impractical, making a conscious effort to stay on top of your inbox goes a long way.
15. You're rude.
Doing good work doesn't matter if no one wants to work with you . Not only does rudeness alienate co-workers, but most managers won't tolerate abrasive and inconsiderate employees. Remember, being polite is a key to winning people over.
