Let's talk about water and wifi
Two things I take for granted on a daily basis.
In Nepal, water from the facet is unsafe. Drinking it can lead to illness. This is why there are water bottles sold everywhere. I carried around a filtered water bottle I bought in the United States and an extra water bottle just in case. This makes my backpack a little heavier but it was better than not having clean drinking water.
In Nepal wifi is also a rare commodity. The hotel we stayed at in Kathmandu had wifi but it rarely worked when all seven of us want to use it. However, we learned that the early a person got up in the morning, the better the wifi was. Although buying data and recharging a SIM card wasn't difficult in Kathmandu, it's an unnecessary expense when free wifi can be found all over the city. I tended to frequent restaurants that offer such a perk. All I have to do is ask for the wifi password when I order food.
