I think that 14 years old is too young to specialize. Your free time, which for now is plenty but will become less and less, would be better spent exploring and learning ad many things as possible according to your personal interests rather than following the job market. The next 5/10 years will be times of great change for you and you never know what will come your way, so the more things you know and explore the more opportunities you will have. You will have plenty of time to specialize once you know you are on the right path. That is to say, if you find COBOL and Fortran interesting go for it! But after 6 months or a year consider trying something else.
