If you want to be a linguist, be a linguist. It’s your life to do with as your choose. Your parents can make suggestions, but they can’t force you to pursue one career if you want to pursue another. If studying languages is your dream, do it. You’ll only regret it in years to come if you don’t.
One thing that does occur to me is to ask whether you are able to pursue your languages in the armed forces in some way. The armed forces always need skilled linguists to work as interpreters, intelligence officers, and diplomats. You may have heard of the British politician Paddy Ashdown (also called Lord Ashdown of Norton-sub-Hamdon). During his varied career as a Royal Marines officer, Special Boat Service commando, Secret Intelligence Service agent, and as High Representative for Bosnia and Herzegovina, he learned six languages in addition to his native English: French, German, Mandarin Chinese, Malay, Bosnian (Serbo-Croatian), and one of the Dayak languages from Borneo. Paddy Ashdown in fact didn’t even complete secondary education before joining the armed forces at the age of 18.
Of course, you may not want to be a linguist in the armed forces. You may want to be a translator, interpreter, teacher, or a scholar of literature. Whatever you decide, you should follow your own dream, not something your parents have chosen for you.
