Well, it seems that the hand rubbing helps, at least.

From what I've heard, it's common for the first lucid dreams to not last long, some wake up as soon as they go lucid. My best advice is to not give up, keep working on lucid dream frequency, and you should have them last longer.

It could also be a good idea to stop by the Dream Control section, and read some threads and look for tips there. I'm sure others have more suggestions.

And welcome to Dreamviews!
