What can you do with a skeptical person?

Skepticism is natural because we are all born with skepticism. You can't remove or avoid because it's inherent in human beings.

But skepticism increases with ignorance, because lack of data. When there is no information on a particular topic, the comfortable position is skepticism. When someone says he is skeptical about a certain topic, you can be sure that only has two or three pieces of the puzzle and with just these two or three pieces, he or she thinks of the whole puzzle.

There's nothing that can be done with this kind of person. No need to convince them and have patience. Don't forget that they are not interested in the puzzle, they prefer the comfort of skepticism.

Also, you have to keep in mind that "who is in time to know does not need proof. Who is not in time to know, any evidence is not enough."
