Please enlighten me...

I can definitely say that the WBTB method of inducing lucid dreams is very effective...
I have 4 to 5 LDs every week using a variation on this technique so thank you very much...
However as soon as I attain lucidity The thought that I simply must do something meaningful occurs...
and being uninformed about the actual goal of lucid dreaming I fiddlefart around for a while change dreams a few times, fly around and enjoy pushing my head through windows and walls...
If anyone can guide me to the next step I would be more than grateful...

Not sure I understand what you mean with "the next step" but if you're looking for things to do then you might want to have a look in this thread:

Lucid dreaming is a great way to explore and experience those things you cannot do in waking life. The sky is the limit! Explore!
