10. How Intoxicated They Like to Get

You might think talking about how inebriated you were over the weekend has no effect on how you’re viewed at work. After all, if you’re a good worker, then you’re a good worker, right? Unfortunately not. Sharing this will not get people to think you’re fun. Instead, they will see you as unpredictable, immature, and lacking in good judgment. Too many people have negative views of drugs and alcohol for you to reveal how much you love to indulge in them.

11. An Offensive Joke

If there’s one thing we can learn from celebrities, it’s to be careful about what you say and whom you say it to. Offensive jokes make other people feel terrible, and they make you look terrible. They also happen to be much less funny than clever jokes.

A joke crosses the line anytime you try to gauge its appropriateness based on how close you are with someone. If there is anyone who would be offended by your joke, you are better off not telling it. You never know whom people know or what experiences they’ve had in life that can lead your joke to tread on subjects that they take very seriously.

12. That They Are Job Hunting

When I was a kid, I told my baseball coach I was quitting in two weeks. For the next two weeks, I found myself riding the bench. It got even worse after those two weeks when I decided to stay, and I became “the kid who doesn’t even want to be here.” I was crushed, but it was my own fault; I told him my decision before it was certain.

The same thing happens when you tell people that you’re job hunting. Once you reveal that you’re planning to leave, you suddenly become a waste of everyone’s time. There’s also the chance that your hunt will be unsuccessful, so it’s best to wait until you’ve found a job before you tell anyone. Otherwise, you will end up riding the bench.
