Grandmasters

Hello, you may have heard of will taylor, aspiring to be a chess grandmaster. I have the same ambition. My rating ( FIDE ) is 1537, though , to be honest im underrated. My low rating is because im not consistent and blunder sometimes ( positionally only, not tactically) . Could you please tell me a study plan for achieving my dream? im 12 years old, have around 10 hours a week during school time. And also, and important question : Do you need to be an aggressive and attacking player like Alekhine to be the best? Please reply it means a lot to me. ( Btw, my USCF rating is 1808, more reflects my abilities ) Please dont give me the usual, solve tactics thing.  Please reply asap.

Appreciate it,

eightsquare.
