New to blender Need help Please

I am very new to the program and ive been trying to model a glass.Just starting out basic.I’ve got the extrude part down and i can get the glass completed but it comes out flat.Can some one tell me what i need to do to make it round like a glass should be.

Thanks,

Maybe start with a cylinder? Or start with a circle around the rim or base and then extrude the entire circle over the glass. It just sounds like you are stuck in 2D. You have to adjust your object so that it looks correct from all 3 views.
