Hey guys!

So I have been lurking for some time now, and I have noticed how you should get rid of friends that are holding you back. (harrasing, keeping me down, commenting etcetc...)

I think I have some friends like this, but I am really unsure of the whole deal here.. Need some help.

So what I'm asking is, How can I notice when it is time for me to get some new friends? Can you give me some examples of a bad friend? Or give me an example of a situation where I should notice that a certain friend is bad for me?

Edit: Thanks for all the replies. I've decided to cut them.
