Lean or not, one big lesson I learned is not to implement a feature until somebody asks for it. This is a surprisingly difficult thing to do, if your mindset has been focused on building things for a long time. If you are not aiming for commercial success, usually building things not necessarily require validation. You can often build for experimentation or fun.

After spending weeks on building and removing features, if I now catch myself building something, I ask the question, "who told me to do this?" and often refrain from doing it.

One hidden power of not building is the simplicity that it brings. You have one less feature to maintain, and you probably save weeks of quality engineering time by not having that feature.

That's actually very clever advice. Thank you.
