Things I've learned so far:
- Never pass up an opportunity to charge your laptop/phone.
- Bring noise-canceling earbuds.
- Always travel with at least $40 in cash.
- Bring a second pair of pants.
- "He who travels happily, must travel light"
- Don't be a lemming: why rush to be first on a plane?
- Never check a bag if you can avoid it.
How about you, any travel tips?
