“The goal of adulthood is to let go of the other possible existences and to make the best of the one. A successful adult is one who understands that it doesn’t matter which life you ultimately pick, only that you live it well.”

From (spoiler alert you have to actually read the article not just the title): [A Surprising Number Of Teens Think They’ll Die Young, Or Live Forever, Whichever Comes First][1]

But, back to the quote, it’s actually pretty spot on if you think about it. Somewhat difficult to do, but living your life well (however you define that) seems like a worthwhile goal.[1]: https://thelastpsychiatrist.com/2009/07/a_surprising_number_of_teens_t.html
