Problems in Your Family
Family matters should always stay private. If you’re having some issues with members of your family, try to sort it out with them. Doing so is much better than complaining about it to a third party.
Having dreams is vital. It helps to motivate you and give you something to look forward to every single day. Although you may be excited about your goals, you should probably keep them to yourself. That way, if you succeed, people will be pleasantly surprised, but if you fail, no one will need to know.
Who You Like and Dislike
No one likes everyone, but that doesn’t mean that you should go around bad-mouthing the people that you don’t like. Even saying that you dislike them without telling why can be enough to make you some enemies. As well as that, never go spreading gossip about other people, it’s just a nasty thing to do.
Financial Status and Salary
Sadly, money is a touchy subject for a lot of people. Some people are going to hate you if you make too much money and others will look down on you if you don’t make enough. Therefore, it’s far better to keep that kind of information to yourself.
Your Biggest Fears
Sharing your fears with the people in your innermost circle is fine, but it’s not a great idea to tell anyone else. Unfortunately, the world is full of terrible people who may try to use this information against you. If they find any weakness in you, they could try to exploit it.
There’s a reason that your medical records are strictly confidential, they are for "your eyes only". No one else needs to, or should, know about your medical history. Of course, there are some exceptions to this, but in most cases it’s simply best to keep quiet.
Issues in Your Relationship
So, you had a fight with your significant other and you want to complain to someone about it. Now, when you and the person you love are happy again, that other person is still going to see them as a bad choice for you.
