To this date, schema-dts is the only side-project I have that achieved better-than-moderate success. It took several hours between the time I had the idea for schema-dts and when I had a reasonably working v0.1. I pulled an all-nighter—something that I hate doing and would never recommend—not out of sheer passion, but because:

• I knew how rare a moment of inspiration is, and
• I knew that if I went to sleep, I would never finish this project; there’s a graveyard of unfinished projects haunting me.

In the Unity for Software Engineers series, I give an accelerated introduction to game development in Unity. Subscribers have been following this series over the past few months, often suggesting areas to cover or elaborate on. A few months ago, a reader—also a software engineer—reached out to me (lightly edited, emphasis mine):

The biggest unknown for me is: How do I start? What does the process of creating a game look like? Should I build the scenes first? Should I design the gameplay mechanics first? With business software, it’s much more familiar. It’s easy to think, “Well, okay, I need to write the DAO or controller, etc.” But with games, I’m lost.
