Guess I'll answer my own question, since this thread flopped.
I think most people would agree that mediocrity is an undesirable thing and would associate it, as I do, with not achieving success. But then it's important to evaluate our notions of success. I started reading a book yesterday called The Queer Art of Failure, in which the author states, "I argue that success in a heteronormative, capitalist society equates too easily to specific forms of reproductive maturity combined with wealth accumulation." And this wealth accumulation seems to remain our standard of success, despite the fact that we've all been told a million times that "money can't buy happiness." And I started thinking about high school, where we vote on who's "most likely to succeed." What are we really voting for? Most likely to get rich? It irritates me that this one view of success is imposed on all of us, because it's certainly a shallow one.
Accumulating money and possessions is a lot of people's main goal in life...but what a waste of this existence that is. In the end, you can't take your money and possessions with you. I agree with you, [MENTION=5224]Sadie[/MENTION], that a life well lived, a successful life, is one filled with love and compassion. I like to think that we can take our love with us when we leave.
So when it comes to the expectations we have for our own lives and the behavior of others, I think there's too much pressure to achieve and accomplish. Because what is the value of any achievement that does not come from a place of love? I think that love, kindness, and compassion are the most we should expect from anyone, no matter how small the display.
I'm interested in hearing others' opinions on the matter.
