I don't think that I could give you any advice...partly because you've already gotten some good suggestions here...and partly because I seem to have the exact opposite problem. I am by nature a very passive person and even though it doesn't really interfere with my independence, I must say that it makes things very difficult for me. Its not so much that I don't have my own opinions or that I'm afraid to voice them...its just that when I do, I'm usually horribly subtle. I wish I had it in me to take control of certain situations, but I find it extremely hard and often I just feel as though its forced, unnatural, or that i've embarassed myself. I just wanted to let you know that I admire your dominant personality and I'm sure that you'll find a way to avoid coming off as abrasive while still preserving your independent outlook

goodluck!
