There’s a difference between pain (and discomfort and effort) and injury.
When we’re in “pain” we often give up.
Now, I’m not talking about doing things that create injuries, more the things that we say: “oh what a pain that is” about.
Injuries are when things get damaged and need to heal.
Pain, discomfort, and the like are temporary, and not to be avoided (at least not all the time . . . ).

The key take-away here is: persevere through pain and discomfort, take care of yourself when injured, heal yourself when necessary.
