I am very cruel to myself. I demand perfection, but I am very lazy. I want to become great, but I fear the result of becoming misunderstood. I desire to be loved, but I panic at the thought of becoming rejected. I yearn to heal, but I long for the things that destroy me in the end.
If Danny doesn't want to fight ghosts all the time then he should destroy the ghost portal. Of course, his parents may build another, but he could tell them that they're putting lives in danger by allowing ghosts into their world.
