Advice for an intermediate-ish programmer?

I know the basics about Lua, and I can make some decent stuff, but I would like to start learning about some advanced things. So please post below stuff like that.

Go make an awesome gamemode or something.

I tutor a lot of people on a daily basis. If you have a quick question you want to ask I’m more than happy to help. I do also offer tutoring sessions and am building up a huge tutorial library and have just started adding quizzes / homework assignments. ( I’m working on designing a course plan around GMod and Lua because I used to teach highschool students, highschool teachers and college students different languages such as Java and Android Development, Scratch / Alice, Python, C++, and more )

Here’s a thread with some good learning resources: http://forum.facepunch.com/showthread.php?t=1337945

Thank you guys for your posts, I hope they improve my work a lot.
