Things do not happen. Things are made to happen.
- John F. Kennedy
This quote feels very timely coming on the day of the successful landing of Curiosity on Mars, both since that certainly is something that was made to happen and since the same speaker famously challenged the US space program to land a man on the moon in a decade.
It applies to our writing, of course, as well. Our stories can't write themselves. We have to be the ones to sit down and do the work. Make the time to make the things you want to see happen, happen.
