If you know how to do it well, you just do it well, its hard work but dooable. What is harder is learning to understand why what was written, that looks good, is actually bad. Usually something small, tucked away, or an issue arising from multiple things spanning distinct functions that culminate in a werid issue. That kind of detective work is draining and time consuming. It doesnt come with the emotional boost of looking at your work and feeling pride. Instead you look at something that finally works and feel releif that its over. That alone paves the way to a totally different emotional and cognitive relationship with your work. That is why for me, at least, it is more cogntiviely intense.
