What programming language to start with?

Ew Python? I never learned it yet, but if you want to learn OOP, I recommend learning C#. I don't recommend starting low as of vb.net cause it's gay. Start with C#, make your way to C++ then C. Any other languages beyond these you'll have a clear understanding of real low level program. Do some fun stuff like learning binary, or playing around with writing your own software.Learn some real stuff, like real assembly language.
