Your biggest non-technical hack/discovery
thesethings: * Cooking: Ramen can be used not just for soup,  but for stir-fry.* Travel: Any supermarket is your fee-free ATM. (cashback) (US)* Travel: In the middle of your urban trek and have to pee? Hotel lobbies usually have clean, open bathrooms. (Specifically talking about the one you're NOT staying at, when you're wandering for 10 hours in a foreign city, and don't want to go all the way back to "base.")* Travel: Hotel lobbies often have free wifi.* Cooking: Peel an orange inside the produce bag. Makes for perfectly dry, not messy, not sticky experience. (your fingers can poke through the skin and tear it, and it doesn't tear bag. Magic.)* Travel: I have so many Priceline and Hotwire strategies, but the short version is: use these sites to book hotels.
