Try doing what other people are asking you to do. Try taking their advice. If you don't, you won't know whether it will work for you or not. There are certain circumstances to which you won't accept other people's words at all because it's something completely stupid, but if it's advice you catch yourself giving others, try it. It might just work.
I do this all of the time. I give advice and help other people, but when I need advice, I can't ever think of what I've told other people. I don't take my own advice. I'm working on helping myself, with the words that I have said to others to try to help them. Try. That's what I need to tell myself.
