Not recommending the career does not necessarily mean that the passion has gone (although it might!). It's not difficult to convince yourself that you want to be a pilot so much, so much more than anyone else that you WILL have the determination and WILL make it. It's only once you are either in the unfortunate but common position of being qualified and jobless OR whenever you are in the job and can full understand and appreciate the downsides that come with the good bits that you can admit that, while it might be a good career for an individual, it is not what it is often portrayed as by movies, the general population and flight schools.
Now you are looking at risking a massive amount of money to fight/compete with thousands of other hopefuls, most of which will think that they are determined enough and can make it. At the end of training there is not a good chance of gaining employment, there is really a pretty poor chance (although this thread admittedly shows a better rate of those employed than I thought it would, but the fact that a number of posts talk about completing training in a much better financial climate must be considered). Then even if you do get a job, there is a good chance that many would be disappointed if they have not figured out the realities.
