Sure, but not clear what it is suppoosed to mean. Unclear what "results I get" means. . The difficulty of this task doesn't match the reward I receive (for doing it)." - sounds as if it is hard work that does not get rewarded adequately. . Sanding the floor is backbreaking work. The results I get don't match the difficulty of this task = it's not worth it.

Asi como lo dijiste está bien

Debes especificar a qué te refieres la tarea de escuela o de trabajo y es de escuela puedes decir la calificación de esta tarea

I mean it's too difficult and the results are not worth doing it.
