How do I know when it's time for me to stop learning old maths and start making new maths? I feel like I am unable to make new maths after trying hard for a while... because I guess I am not familiar enough with the old maths... But then I try to learn old maths all day long for months, even years on end; and end up feeling like I've forgotten all I've learnt anyway... So then I went back to trying to make new maths and failed again... So I've gone back to learning old maths, but it seems like its going nowhere again... Am I going to be stuck like this forever or will something new come out finally?
how about learning science
