A wood ship is a one step at a time achivement. Leave it, come back do a bit more. There are long repetitious things to go through,but sometimes those are the most relaxing. Some hate rigging, I love it. Ratlines are extremely repetitious, but because they are so simple, move, tie a knot, move tie a knot. Get to the end, do it again. Its extremely relaxing as you think about nothing else. The suddenly you look up and see what you have created from nothing and have a wow moment. Those that dont build ships do not get it, but those that do realise the magic and sit back and go 'I did that !"
