The majority of the time, traveling is about the journey than the destination, except for a few adventurers. If you travel with just what you want, your travel choices expand rapidly.
Carrying one little bag instead of multiple suitcases speeds up all types of public transport, from getting on airplanes or traveling on trains. The less you need to take care of, the faster everything goes.
Packing light increases your traveling flexibility. Traveling with more luggage leads to airline prices. Even if staying at a resort, the lightweight traveler gets the benefit of worrying less about the luggage.
If you travel light, you won't need to be concerned about all those "important" things. No longer babysitting, or being always concerned about theft or loss. You will also be less inclined to become a target of thieves since you will not be carrying a lot of bags.
Having a little backpack is far easier to get around. You can go on a date or ride a camel to historical ruins without being confined by material things. If you wish to stay in someplace, you can. If you would like to leave, then depart.
Another one of the benefits of traveling light is your traveling costs return. No more will you get billed check-in luggage charges in the airlines.
