Heroes:
Hey Hero! You're at another turning point in your life but what else is new? That happens every few issues, doesn't it? It feels like everything is spotlight and immense, but it always does. That's what a spandex life is like, larger than life, in all senses. But that's a fractured life, split between your main title and those team books and the backstory and the plot threads that some editor forgot were left in loose threads. Don't be overly concerned that you can't make all those plot threads tie up neatly into a pretty bow. The decisions you make now do matter, but they'll be playing out over months. Just let your daydreams flow without analysis, and your worries go without obsessing. As much as you can. After all, if that obsession is your raison d'etre then you are stuck with that bit of canon!
Villains:, Life is full of turning points, Villain, and you know perfectly well that observer bias makes each one feel more important than the ones before. But in the real four color world, this one might not be as big as it feels. It's true that these choices do set your new direction, but even a powerful and puissant bad guy or gal like yourself has limited knowledge of the future (you prescient types can just skip today's 'scope, but you already knew that because you're prescient!). Don't be too concerned if you can't figure out how to get your desires and goals to harmonize perfectly; a little dissonance keeps things lively and lets new tunes emerge! Just keep humming along and give those tunes time to reach the chorus and bridge, and you'll have a great metal tune of malice on your hands!
