Yes with the experience you wud become a SEO expert. Just try to discuss as much as possible on DP as well as on other Forums also. It wud help you lot.
It's definitely not easy to become an SEO expert. You've been given a lot of great responses. However, bottom line is results. Talk is fine, and someone can sound very knowledgable, but if they can't actually produce results to back up what they say, then they are not an expert. Time, knowledge, and experience are all required...and none of them happen quickly.
