Best way to learn lua?

I've been scripting for about 3 months now and have come to the conclusion that the Roblox scripting wiki is completely useless to a more advanced scripter besides listing all possible functions. Im reading the lua first edition and im making my way to the second edition (im almost done reading the Roblox lua Wiki as well) is there a better way to learn besides reading these 2 books and the Wiki because they just aren't doing a great job at helping me become the great lua scripter I wish to become. Any help at all is greatly appreciated, so feel free to leave book titles, tips or helpful comments. :D -DuckDude33
