Should you keep to yourself

Sometimes its best to keep to yourself, but it's OK to let people know where you stand. You don't have to yell it out to everyone. As in you don't have to give out free information. If someone asks a question about you, give a fast, but true answers. You don't have to explain yourself if they didn't asks.
However, people only need a little information to keep them asks for more and a little is a lot. You will see more +s and you will see people for who they are and you didn't give all your time to them for nothing. SO, No! Don't keep to yourself go slow and listen to them, before you say a word.
