Can't read the artice but I do have some generic observations. Most projects aren't going to work, so that can be one of the primary goals, mainly to find out whether or not that's the case, without too many compromises. So most of the time to be realistic you have to try real hard for it not to work quite early on, or that could be something where you end up wasting too much time on a hopeless effort. Some people never quit, and it can be difficult to know when to mothball something or give up altogether. Mothballs can be your friend, especially when there are a greater number of promising projects than could ever be fully completed anyway. Progress can surprise you though, but more often than not many things will take an unexpected downturn before you ever see a case of an unexpected upturn.
