It's like one of those 80/20 rule things. Something like 25% of any given project is the 'fun' part. These include refining the basic idea; building a prototype; getting some simple functions working; seeing it do one or two things extremely well. The other 75% is the 'grunt work' part that may not be fun to work on (e.g. documentation, bug fixes, refactoring, etc.) but is often absolutely necessary to have a 'finished' project. (Not that any project is really ever finished, but rather one that is usable to a large audience) I have experienced this with various projects I have worked on over the years; whether ones I worked on professionally while working for someone else, or my own 'hobby projects' that I did in my spare time.
