As Unpredictable as Weather (sonnet)

"Moderation in all things," so they say.
Why can't I seem to ever follow that?
Extremes are my buddies most ev'ry day;
I'm left feeling I've been run over flat.
Why can't I ever find the right balance?
Why do I make things a competition?
Why don't I give myself more of a chance?
I get steam-rolled by my own ambition.
Bigger, faster, and more are not better,
But nothing isn't really all that great.
I'm as unpredictable as weather --
What if this will forever be my fate?
I need to find a way to mellow out,
But I don't understand what that's about.
