8 items in my carry-on

As I travel across Europe for market research the last 10 days, I wanted to keep my carry-on bag light, but still stay productive.

I saw a feature in the Lufthansa Magazin that asked "what's in your bag?"

Here are the 8 essential items I've been carrying.

1. Laptop
2. iPad
3. Notebook
4. Noise-cancelling headphones
5. Phone plug and back-up battery
6. Sunglasses
7. Receipt envelope
8. Neoprene sleeve case
