Find a server.
See somebody building something cool.
Ask them to teach you how to do it.

People in Gmod are generally pretty happy to teach newbies, even if it's only to show off vOv
(after all, that noob today is all to often teaching you crap in 6 months :C)

Or, I can keep barrel spamming, and figure out how to make my own shit in 3ds for gmod!

and then get all the cool kids to put it in their servers!
