I went up this morning and talked to the neighbour right above me. For the past 5 years he always makes a lot of noise doing woodwork inside his apartment. I asked him politely and he was a little ironic. I kept my cool and told him I am a writer and need a little quiet but regardless, I pointed out it was unacceptable. I get up at 6 am and do yoga and mental work while he is pounding on some shit (even at 6-7 AM). This was not just today but a constant for the past few years.
Moral of the story? It's a losing battle. Just ignore if possible. I am not going to knock him out because he looks like a tormented soul. At most I will file a complaint with the local police dept but I doubt it will have any effect (neighbours did this in the past and it still goes on). So I just go on about my business. You cannot impose your will on someone. It's a losing battle.
