It would be interesting to know what he actually thinks but I know because I have actually been in that situation (unf, more than once). It isn't fun, it is soul-destroying to pour your being into something you love with no reward. Even if you are "successful", that initial experience of feeling trapped taints it (indeed, the whole point is that you are immune to notions of success/failure and the experience changes your notion of success...if you come into thinking about success then you will get washed out in a few months).
And he was successful despite it. He would have done okay whatever he did. It is just a little unfortunate that he had go down that path, imo.
