Bitty, I agree with just about every thing you said except this one thing:
Be careful when asking your friends particularly males for advice. Women are usually seen as the bitter gender but believe me there are plenty of men out there who are very bitter and in turn have usually very low opinions of women in general. So almost all of the advice you get from these guys will only hurt you if you act on it.
I'm not gonna get into stereotypes. Men and women can be bitter. I've seen a lot of it on both ends, and for that matter, I USED to be bitter. So you're right that you definitely want to ask a bitter person for advise on the opposite sex. However, I think it's VERY important to be talking to your friends and taking their advise if they aren't bitter and if they have a good head on their shoulders and if they've been observant on things that happen around them.
However, in the end, it's YOU that has to do the work and you have to have your own plan and YOU have to live your own life and do the things that make you happy. More importantly, you have to make sure that you NEVER put yourself in a position that you need the opposite sex (Or same sex for the gays) to validate your life.
Your faith, friends, family, career aspirations, financial priorities, enjoyment, health and your passions should ALL come before opposite sex. The women or men should come automatically come when you get all of that straightened out.
