I've been learning Morse code for just over a year and it is hard, but I've been getting better at decoding in my head.
There are some great tools out there. On my phone I use MorseMania (https://dong.digital/morsemania/) and when walking around I listen to audio files from https://morsecode.ninja.
I love that it is a "data" mode that humans can do. It also means I can minimize my gear to a very small, low-power radio with a small wire antenna and talk globally
