Pour the water and sugar into a small saucepan. Cook it over low-heat, stirring often, until the sugar is dissolved. Let it come to a boil, then set it aside to cool. How much sugar you use will depend on how ripe and sweet the mangoes are. You can also buy some simple syrup from the store and use that instead. You will need 1 cup (240 milliliters) of simple syrup. Peel, seed, and cube the mangoes first, then toss them into the blender. Puree them until they are smooth. If you need to, pause the blender and push the mango pieces down the sides of the blender with a spatula. This will make the base for your sorbet, and make it easier to mix the rest of the ingredients. The lime juice is optional, but it helps cut the sweetness of the sorbet. It also helps add another layer of flavor to it. If you don't have lime juice, but still want to add something, try lemon juice instead. If you have an ice cream maker, be sure to follow the manufacturer's directions closely, as every ice cream maker is different. It will take about 20 minutes. If you don't have an ice cream maker, pour the puree into a shallow baking dish and freeze for 2 hours, stirring with a whisk every 30 minutes. Use a spatula to help guide the mixture into the container and to smooth the top down. You need to do this regardless of whether or not you used an ice cream maker. It will help "cure" the sorbet and give it a smoother texture. You can also scoop the mixture into empty mango skins, and freeze them that way. For a creamier texture, fold in 1 beaten egg white; make sure it's been beaten until stiff peaks have formed first. Keep in mind that egg whites may contain salmonella, especially if they have not been pasteurized. You can serve it as it, or garnish it with a mint or basil leaf for a pop of color. Freeze any leftovers promptly; it will last up to 1 week in the freezer.

There are many options for free or cheap travel through doing a specific job. However, most come with significant responsibilities. There are numerous online resources for finding these types of jobs. Try searching for a job title or description and a location and see what comes up. Some of the opportunities to consider include: Moving yachts around the world for absentee owners or working as part of a crew for active yachts Delivering packages by hand as a courier on international flights Traveling as part of the crew on container ships (hard work!) Being a tourist guide (hiking trails, tours of historic buildings or ruins, etc.) Driving vehicles from one location to another location Teaching your language in another country This generally involves only a simple online signup before you're on your way. Organizations like CouchSurfing, Servas International, Global Freeloaders, and Hospitality Club allow you to stay with strangers for free or in return for some simple labor.These services are operated through an online network and operate all over the world. Be sure to follow all the safety protocols in place and look for people who have a lot of good referrals, to be on the safe side. While the idea is to meet friends you've not yet met, always be cautious when meeting with strangers. Home swapping can be another good choice if you own or rent on a permanent basis. There are plenty of opportunities available online; just be sure to do all necessary checks to ensure you're not inviting a house destroyer into your home! Check out http://www.caretaker.org to browse available opportunities. These vary from seasonal (beach houses, ski cabins, or homes where the residents are going away for a few weeks, months, or even years and need the house cared for), to permanent positions where you are essentially a "caretaker" of such places as hostels, retirement homes, lighthouses, organic farms, ranches, motels, or campgrounds, among others. If you're looking for a comfortable and fairly extended length of stay in a place, and obviously if you want to be a caretaker, you'll need an established track record, possibly training in hospitality, and good references. But do persevere as this can be an incredibly good way to live cheaply. If you get a role as a caretaker, expect to do such tasks as taking tourists around, caring for animals and gardens, property maintenance, ensuring security measures are in place, cleaning pools, etc. Note that this is one role where "reverse age discrimination" is rife, as property owners want mature and reliable people over a certain age. Get out and see the world. Whatever your age, you can help others in your own country or overseas. If you're willing to volunteer organizations in such areas as health, reconstruction, conservation, sanitation, providing food and shelter, etc., you'll find a steady stream of free accommodation and food in return for your volunteering. In most cases it's not likely that you'll get paid much, if anything at all, but the reward of free shelter, food, and doing good for humanity can be worth far more than a wage. If you have children, this option is harder to accommodate but some families still give it a go by checking out in advance that there is good schooling and decent living standards available; an experience like this can shape kids dramatically for the better, so don't dismiss it outright. One other, fairly drastic, change is to move to a country where your savings go a really long way. Search online for expatriate resources for global relocation; there are enough people doing this to warrant a small industry catering to them! Just remember, living on practically nothing requires effort, as with most good things in life, so don't equate it with doing nothing!
