The Physics of Side Projects

A data-driven guide to why most side projects stall — and how to design motion that lasts.

From 1,000+ projects, one simple pattern emerged: momentum is a system, not a feeling.

The Physics of Side Projects book cover

Most side projects don't fail because the idea was bad — they fade because momentum decays.

If you're a builder, you've seen it before. The early rush of energy, the long to-do list, the quiet slowdown.

The Physics of Side Projects explores why that happens — not from theory, but from data.

It unpacks how scope, friction, and feedback loops interact to make or break progress — and what builders can do to sustain energy without burning out.

What's inside the guide

The Four Forces of Builder Physics

How energy, mass, friction, and velocity shape every project's motion.

Momentum vs. Motivation

The science behind why consistency beats inspiration.

Empirical Patterns

What 1,000+ side projects teach us about longevity and traction.

Practical Self-Test

Simple signals that show whether your project's physics are working for or against you.

Each page is built to give you practical insight — something you can apply immediately to your current side project.

Built for technical builders who think in systems

This isn't a marketing eBook or another productivity listicle.

It's for makers, indie hackers, engineers, and founders who want to understand how progress compounds — and how to design projects that sustain traction without losing flow.
