I can't bring myself to see editorials. At least not before I have solved a problem. Of around 700 problems I solved, I have seen editorials less than ten times. So it takes a lot of time for me to solve hard problems, lasting usually from 2-3 hours to a few days, and sometimes a few months. Now, it is quite inefficient, but I still want to rely on editorials/tutorials as less as possible. Relying on editorials ruin my experience and interest. How can I improve my efficiency without relying on editorials
