Quite a Commencement Speech

 If you find yourself in such a place, I would ask you to consider a rule I learned as a physician: First, do no harm.

Besides, life is not that short. Life is well and long enough for you to come to regret any activity or habit
involving an exchange of long-term risk for short-term benefit. This is what many if not most Americans
did during the refinancing and consumption boom of the last decade, and it was what our government did
in egging on the boom. This is also the gospel of drunk drivers and cheating spouses.

Of course, when you encounter the opposite—the short-term risk exchanged for long-term benefit—
consider hitting that button again and again and again.

Past may be prologue, but this is not true for the individual. The individual can think different

What I tell my Daughter when she cries

Hold on, to me as we go
As we roll down this unfamiliar road
And although this wave (wave) is stringing us along
Just know you're not alone
Cause I'm gonna make this place your home

Settle down, it'll all be clear
Don't pay no mind to the demons
They fill you with fear
The trouble it might drag you down
If you get lost, you can always be found

Just know you're not alone
Cause I'm gonna make this place your home

DFW on Certainty

Part of our emergency is that it's so tempting to do this sort of thing now, to retreat to narrow arrogance, pre-formed positions, rigid filters, the “moral clarity” of the immature.

The alternative is dealing with massive, high-entropy amounts of info and ambiguity and conflict and flux; it’s continually discovering new areas of personal ignorance and delusion. In sum, to really try to be informed and literate today is to feel stupid nearly all the time and to need help.

That's about as clearly as I can put it ... That last one's of especial value, I think. As exquisite verbal art, yes, but also as a model for what free, informed adulthood might look like in the context of Total Noise: not just the intelligence to discern one's own error or stupidity, but the humility to address it, absorb it, and move on and out therefrom, bravely, toward the next revealed error.

This is probably the sincerest, most biased account of “best” your decider can give: these pieces are models — not templates, but models — of ways I wish I could think and live in what seems to me this world.
— David Foster Wallace
