Some important rules when considering adding ML to your app:
1. Start building without machine learning
2. Continue without machine learning
3. Be blissfully unaware of concept drift, model versioning, AUC, and feature engineering
4. Turn off the computer
5. Go outside and buy a small child an ice cream cone
6. Sit with your beloved under the stars and, wonder at the vastness of the universe and your small role in it
7. Turn the computer back on, you’re now ready to add only linear regression
