Good day Sir. In terms of choosing career, parents role is to just advice and help the child view and analyse the advantages and disadvantages of the career. The final decision is left for the child.
Parents are doing the above because it's possible the child is just picking career randomly. But when the child is able to think clearly, then parents is to guide and support that's all.
In conclusion parent should not choose a career.
I don't know if I have answer you sir.
