    Had a peek at the Dutch for coming days, breakfast is impossible, lunch 50% of the time, dinner is easy. Perhaps I could take left-overs home and reheat them for the missing breakfasts and lunches. 🍕 Getting drunk for free each night looks easy 🍻

    Idea: Make a small documentary about living an entire month only on visiting Meetups/user group meetings. Joining random free meetups every day, not buying anything, no food, for a month. Great for connecting to people and learning new things, can you ever have too much pizza?
