Ignore the posted advice. One of the things you don't mention is your gender. If you are a woman, you are probably being ignored and labelled aggressive because you want to be treated well. If you are a man, you don't fit in. You need to be on top and the only way you can do that is self employed. Go for it. Time is wasting and if you are who you say you are, your temperament means you are hardworking and results oriented. You should be a success.
