Should I learn to read an analog clock now that I am 22?
Maybe. Is there a specific reason why you need to read an analog clock now that you are 22?
I've been having issues with being punctual
Some people grow up not knowing how to do normal things they should, but there is always a way to learn. Get someone to teach you how to tell time, this prevents everyone from being late. Everyone needs to learn that to function in life.
But I really don't want to learn it and maybe it's okay if I'm late.
It is okay if you don't want to learn how to read an anolog clock, especially when a lot of things are digital. Just set an alarm on your phone and you won't be late.
