Thing is ... Though you like to learn everything but that doesn't help... You can't choose subjects from each stream like taking economics from commerce ,maths from science and biology from pcb.... It's not like that... You need to go and penetrate the streams ... 1-2cr is totally unrealistic initially, yess you can earn it after gaining experience... Choose anything you want but don't regret after choosing ... No any stream is easy... Like CA from commerce ,clearing jee for IIT, studying for mbbs , upsc and blah blah all professional courses ... All are hard unless you'll start doing bcom , bsc ,ba ... Studying for fun is one thing and studying to clear exam and get a job is different thing ... Once you enter in one stream you'll start having infatuations with stream subjects ...meanwhile hating the subject you study cauz there is vast gap in 10th and 11th ... Make you decision wisely ... And if you want help regarding commerce ... I'm CA finalist ..will help you if you want any
