As children and young adults people are taught to "pursue their dreams" and "find their passion" and many other aspirational platitudes.
Then, adult life comes along and most of us become decidedly average because, well, that's statistics for you.
But many are then left with this feeling that they've somehow failed. That if they'd taken that other road that diverged in that wood a ways back, maybe they'd be living that fantasy life that they were sold.
What we're not taught is how to be happy in the present. Aspiring to change is vital to improve ourselves and the world around us. But equally valuing and appreciating what we already have is every bit as important.
