In a month? No way, concentrate on one task for a whole month? Nah... I can do in one day what others do in a week, but after that day (sometimes it can be up to two) the dopamine is gone and I leave that for a couple weeks at least.

At home we wanted to remove an ugly wallpaper and paint the wall, which is behind a bookshelf that takes the whole length. In one weekend we put the books in boxes, took off the whole shelf down, and remove half the wallpaper off the wall. Then a couple of weeks passed until we finished removing the wallpaper. Then the whole thing stayed tore down for a few months. Then finally in another weekend we painted nearly the whole wall (but needed another layer). Then a few weeks passed until we added the last layer, built the bookshelf and then started painting the bookshelf.

Any way, long story short, it took like a whole year to fucking finish it.

My wife has even stronger ADHD so we make quite a fun couple :)
