Dude, first make it through the 2020s, then the 2030s, then the 2040s, etc. Take it one decade at a time, before you plot your 'forever' 'final fantasy'.
But, if you're really serious, then why not use this ambitious thought as the foundation for furthering your excellence?!
It takes roughly 10,000 hours to master a subject. Since time has no meaning for 'forever' you, your work week would be like 4 hours over 5 days, i.e. 20 hours. So, 80 hours a month, and 800 hours per year, assuming a one month break every semester. This means you'll reach that 10,000 hours milestone in twelve and a half years. Okay, let's just say fifteen years!
So, in three decades you'll master two subjects. In one hundred years, you will master six subjects, assuming 10 years washed away in indolence.
So, what will your subjects to master be? The hard problems confronting humanity, of course.
But first, you must make all efforts to become very, very rich. Like Warren Buffett and Bill Gates rich, unless you are lucky enough to be born to them, or you are them asking this question on this off-topic forum for a lark.
