Here’s the thing about subplots. They don’t have to be your best friend, but you should treat them like your best friend’s hot sister. Nobody’s asking you to spend a lot of time getting to know her. (But let’s be honest. Would they have to ask?) Just make sure the time you do invest is quality. It’ll totally pay dividends in the end.
Be good to your subplots. Show them you understand their complexities and you know their worth. Make them believe that their development is as important to you as the other plots that occupy the majority of your day. You wish that you had more time to devote, but it wasn’t meant to be.
You and your subplots are star-crossed lovers. Victims of circumstance, meeting in the wrong place at the wrong time. Perhaps in another life you’ll have more time for each other. Maybe the universe will do you a solid the next time around.
But rather than bemoan what the fates have given you, it’s better to seize this moment, this day, no matter how brief. Cherish the time you have together and make it something special. If time is the enemy, then ally yourself with memory. Write a story worth remembering. One that outlives its own fleeting arc.
