Discouraging might be thing these people actually want to do. I'm not talking about them being evil and want bad for you. But without realizing, you sometimes try to make it harder for someone else when the thing they do is what you can't do. For example, when I don't pass an exam, I (this sounds evil I know) serectly wish my friends to have failed, too. Of course I want them to passed. But I didn't so without realizing, it would be relieving if I wasn't the only one. Now bring this to changing. Sometimes, people don't want you to get further in life without wishing bad for you.
