Pain can be a purpose stimulator if you let it. Save your pity for yourself. When I objectively think about where I am versus where I could have been had I not cared so much, while the trajectory may not have been at stratosphere level it would have been statistically significant. And this matters because that is how it happens. The “it” that I am referring to is the erosion of your time.
Sympathy is when you feel bad for someone else’s misfortunes. Empathy is when you can feel those misfortunes for yourself. If you’ve ever been hungry before then you should be able to have empathy for someone who is hungry. Sympathy is just feeling bad for that person without necessarily any connection to the experience that is worth feeling bad for that person about.
