That's not how I read it...more like "watching a movie about facebook and building my hopes and dreams on this being me in x years" is what you should avoid. FB/GOOG/etc are the very rare outliers. Don't hedge your business (or mental-wellbeing) on the expectation to replicate their success. It's good to have high ambitions but have a plan B & don't expect to be the unicorn. It would be analogous to starting a band in the hopes of becoming the next Beatles.
