I have done this post before. I was new here, and wanted to get some of the valuable information from the regs. I also thought it would be the quickest way to share my new knowledge with the other posters.

Now, even though it turned out to be a very good thread the first time around, I think we can go one better. I'm going to throw out some guidelines for the posting so that we keep it helpful.

1) Serious posts. This thread loses all value if the posts are ridiculous.
2) One liners in bold please.
3) Please feel free to elaborate on your own one liner, or someone elses. There is no idea in poker that can be completely discussed in one line.
4) Everyone post. Beginner, Intermediate, and Expert players all have things to share. No advice is too basic. If it hasn't been said, say it yourself.
[edit]
5) If you make any type of helpful post, AWESOME. Try to stick at least one good one liner on the end.

Above all, remember that one liners are guidelines. Not live or die rules. This is meant to provoke good thinking habits in players of all skill levels.

Beginners: What have you learned so far that has drastically improved your game?

Intermediates: What things have you discovered recently about your play through your study and experience?

Experts: What timeless lessons can you share?
