Misleading. Here's why...
1. Put the phrase in quotes for greater accuracy. That drops the figure down to about 60,000,000.
2. Note that Google eliminates most of these as irrelevant/not very relevant to the search request. In fact, when I just did the search, all results past page 47 were omitted, i.e. Google only found 470 results that were truly relevant to the search phrase.
3. Look at the actual results. For example, the phrase "How to find yourself" often ends with things like "a lawyer," "a doctor," "a pool man," or even "on Google Earth." None of these is remotely narcissistic.
