What can I do with my computer?

What can I do with my computer that I am missing out on?

What I do:
-Huge iTunes Library
-Browse Internet
-Ripped a few DVD's for home theater
-Garageband
-Gaming: I find Macs are a little weak for this compared to consoles and Windows PC's
-Made movies for school film class
-Photoshop
-Rosetta Stone
-Built a basic website

I feel like I am missing out. I am wondering what some other fun projects I can get into. Programming was pretty frustrating. What other programs should I look into? What do you use your computer for that is unique?

 

Yes I was looking for a good architecture program to design a house. That would be fun.
