<human>:  How can I travel to every country in the world?

Generally speaking, to travel to every country in the world, you will need to obtain the necessary visas, have a valid passport, and have enough money to pay for all travel costs and expenses. You should also research each destination to find out what kind of transportation is available, what is required for entry, and any other important information.
