I've noticed that it's hard for me to join a group of people that has more than 2-3 people. Thinking back, throughout my entire life, I've always been in groups of 'only' 2-3, or 5 people tops. I tried doing the whole 'going out of your comfort zone' and getting into groups which had 9-10 people but the vibes they gave were exactly like you said - superficial. You had this constant feeling that the other people weren't above backstabbing/trampling you over to achieve their means. It felt kind of hollow, and I slowly started to drift away from them to meet others.

Do things. Do things that bring you into contact with other people: namely, working with colleagues, rather than customers. (So a soup kitchen counts, but being a solo consultant doesn't.) When they invite you out for doing stuff, join in. You can back out the second time if you don't enjoy it. Get to know as many of them as you can. Share your interests; listen to theirs.

You'll run into someone interested in you soon enough.

Possibly not clubbing to begin with. That does not usually lead to marriage.

I guess to be sincere, be kind, be supportive and always be prepared to listen, treat love given to you as rare, so don't spoil and throw it away. Be there for her.

That's just my solution though I haven't met mine.

I am pretty sure this http://www.artofmanliness.com/ helped me a lot. Not thought dating advice but by helping me to become a better man. I know it sound cheezy, but really you don't really want to trick anyone into marriage.

Dont try too hard.

99% of mainstream dating advice is hogwash.

The best dating advice is concentrated on men who are players or aspire to be. But the skills to seduce a fling and a future wife are very similar.

If you want to catch a great woman, you must have the skills to catch any woman.
