Spend More Time Surfing: Custom Entities & Entity Tools

Entities are one of the most important additions that came to us in Drupal 7. Between what made it into core, and what we gained with the addition of the Entity API module, we have some potent new tools to leverage, including custom entities, EntityFieldQuery and EntityMetadataWrapper. Once you master entities and these new classes your code will be less brittle, your mind will be at ease, and you'll have more time to catch waves. Wouldn't you rather be surfing?
