It helps doing the gdb commands again and again and remember which registers etc are used for. Don't just display the content of the register before the cmp otherwise it's pointless. Go instruction by instruction and see what it's doing. If you're lost because you don't understand why some register was used, why some register is dereferenced at certain offset, tell yourself you haven't completed this crackme and go watch videos to deepen your knowledge about x86-64 asm :D
