Welcome!

That was a great first lucid. You were able to make it last quite a while and do many different things.

I agree that you should keep a dream journal. Not just to improve dream recall, but to also keep track of your dreams and find patterns and reoccuring themes. Plus, it's a lot of fun to go back and reread them. If you start a dream journal on this site, you will also get to have others comment and encourage you. I have found it really worth it.
