Key learnings- Treat intuition as a hypothesis generator: propose hunches, then debate them and test them against data before committing.
- Read customer feedback constantly and dig past stated requests to find the real underlying problem users are trying to solve.
- Ship early to get feedback faster, but hold a firm quality bar, since software can be iteratively improved after launch.
