Less Is More
Instagram launched with one feature: take a photo, add a filter, share it.
No messaging. No stories. No reels. No marketplace. Just photos.
Systrom says that constraint was the key to everything.
Do fewer things. Do them perfectly. That was the biggest difference between what worked and what didn't.
Perfect or Cut
If a feature cannot be made perfect in the time available, cut it.
A half-built feature is worse than no feature. It confuses users and wastes engineering.
Cut ruthlessly. Ship what is left. Make it flawless.
Do fewer things. Do them better.
The Discipline
This requires discipline that most founders do not have.
The temptation to add one more thing is overwhelming. Resist it.
Every feature you add divides attention. Every feature you cut focuses it.
