"Life is what you make it." Meaning that we must always accept personal responsibility for our own lives... our happiness and wellbeing.
I could see some ILI's (or perhaps some LIE's who haven't had enough Gamma Se in their environment) needing a more Se explanation of this concept in order for it to click with them. But still, pretty much every Gamma I've known has felt this way to some extent.
And for the aforementioned Gamma NT's: http://youtube.com/watch?v=TfMKE5b1DyA
This philosophy towards life doesn't seem to ring true with Deltas though...
An LSE may say "sure, whatever you say, Joy " (that is, if they're in a good mood)
An IEE may say "I see what you're saying, but what about *insert lots of Ne + Fi here*", or they may flat out disagree.
And the introverts would probably respond along the lines of " ", especially EII's. SLI's may also just flat out disagree.
