I say as a human being, to develop empathy means to YOU learn and grow empathy skills/mindset. To do that, expose yourself to scenarios that might make you uncomfortable, but you will learn something.
Try to do a day-to-day task that you may take for granted, but do it with a blindfold on to experience what having no vision is like. Or taking a shower for example. If you were bound to a wheelchair, that task might not be so easy for you.
What you will begin to realize (hopefully) are the barriers disabled users deal with, and this should encourage you to try and find ways to help or eliminate those barriers. A real world example of this would be wheelchair ramps or brail signs, and in the IT world it would be accessibility settings like voiceover or a high contrast color mode.
The goal is ultimately expose yourself to different ways other humans experience the world (real and digital), to grow your knowledge, perspective, and understanding … and help to make it a better place for all of us.
