This is a very generic question... Are you interested in the software side of computers or the hardware? Are you interested in programming and if so what are you looking to make software, web pages, apps, games? Or are you looking to learn useful skills such as Photoshop, Illustrator, After Effects, InDesign, Pro Tools, Logic, Maya, Blender, Zbrush, etc.
There's an infinite amount of tools, resources, and knowledge on the internet. Learn whats out there, find what you like, and pursue it endlessly. Good luck!
