ProcessFest Day 2: Where do you start?

I swear to God I am almost done procrastinating on my yagkyas story. Soon I will be procrastinating about Yuletide instead!

I finished my yagkyas story and it is off to beta! Now I can do stuff that is not that with a clear conscience! :D

Meanwhile, processfest Day two:
What's your first spark of inspiration? What makes you decide to work on a new project? What's your first step? Is it always the same or does your method change? How do you begin when you create?

( This is where we start. )
