I don't know how to better explain this, but as I get older I find I just have less energy to address all the things. My worldview gets larger and my energy levels become less and eventually I need to just 'stop' progressing in a certain activity. It could be re-learning the TV's remote control like my grandparents, or it could be re-learning how to drive with an EV touchscreen on modern cars, or it could be re-learning an operating system that just presents a mountain where you just say: "I can't do it this time."
