First proper telescope: what would you tell yourself?

A friend's asking me what to buy as a first scope, and every answer I start writing turns into a warning. My short list:
- The best scope is the one you'll carry outside
- Buy a mount before you buy more aperture
- Binoculars first, always
What would you add?

Learn the sky before you buy anything with a motor. A planisphere costs almost nothing.
