Things I wish I had known when I first started using celery...

1. Minimal startup of celery (no rabbitmq)
2. Starting celery from inside my main app process
3. Setting up your project with a Dedicated Module
4. Keeping celery code separate from your logic with custom tasks
5. Gently interrupting long-running tasks using soft limits
6. Capturing errors and routing them for special/central handling
