I see the potential in my students and can envision how they would shine if they bother to apply themselves and realise their potential. But I don’t let myself think about whether my efforts will lead to favourable outcomes or not. I just give and expect nothing in return. Does that make sense?

Actually I think you may know your sources of anger since you are aware that it’s a set of triggers. But maybe you need to carve out quiet time and work to unpack these triggers. Of course, it’s easier said than done since we have things to do in our busy everyday lives. You may also not want to confront your true self too?
