How do i select the origin point, (The orange circle thing)

Title pretty much sums it up.

You either want to select the object and Object > Snap > Cursor to Selected
(which puts the 3d cursor on the orange dot)

Or hit N (expand side panel) > Tool > Options > Transform > Affect Only Origins


Thanks but my camera still goes around where the origin used to be

You have Orbit around Selection?

What does that mean?
