Hello and welcome to LessWrong!
Bravo! It all starts with finding the crack in the lens. Now comes the hard, fun, terrible, numinous part of living better than before. Since you've already bootstrapped yourself through the sequences, you might want to consider branching out into real space. I say this because it sounds like you're looking for the practical, real, hands-on experience. A LessWrong meetup, such as the one held near London, might be the very thing you need. A group of like-minded people, engaging in rationality exercises, swapping notes, and basically helping each other get a little bit stronger and feel a little bit better.
You might also be interested in the Rationality Diary. It's a good place for starting out tallying yourself, making a record of the real behaviors you've done, the real plans you've made, the real successes and failures you've had.It's a useful tool for keeping yourself honest and seeing how far you've come.
And, of course, if you'd just like to participate in the discussion... well, there's certainly a place for that too.
Glad to have you join the conversation! Hope to see you around soon.
Thanks for the welcome and the useful links, you're right about the tendency towards meetups which is why I'm going to the one in Bath tomorrow. The rationality diary seems like it should be a useful and interesting addition to my attempts at self improvement, so cheers.
Edit: That open thread is fascinating. I've never seen a community with such a high standard of discussion in real time. Even bestof archived depthhub threads don't touch it. I am going to have to think very carefully about any comments I might make to avoid accidentally eternal septemberin...
A few notes about the site mechanics
A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
A list of some posts that are pretty awesome
I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site!
Once a post gets over 500 comments, the site stops showing them all by default. If this post has 500 comments and you have 20 karma, please do start the next welcome post; a new post is a good perennial way to encourage newcomers and lurkers to introduce themselves. (Step-by-step, foolproof instructions here; takes <180seconds.)
If there's anything I should add or update on this post (especially broken links), please send me a private message—I may not notice a comment on the post.
Finally, a big thank you to everyone that helped write this post via its predecessors!
