Seppuku, skepticism is a good thing. Skepticism doesn't merely involve doubt, it involves looking at things with an open mind, and applying doubt as and when it needs to be appiled, as judged by you (after all, it is your doubt, no one else's). There's a term called pseudoskepticism, used to describe people who are always geared to doubt things. That is as imbalanced as always being geared to believing things. Sure there can always be another possible explanation for an event involving a supposed ghost, but we live in a world where certain things are automatically dismissed as nonsense (especially in westernised countries), even by people who don't know all the facts (case in point, we all watch the news, but let's face it, few of us know what's really going on in the world, least of all journalists who get their information from another party), and it's important to remain objective rather than allow our culture to make our minds up for us.
A true open mind is one that is prepared to bravely put aside all preconcpetions of the possible. Many claim to do this but few actually do. The most balanced way to look at a claim is to find all possible conceiveable reasons why it could be true, as well as reasons wht it could not be true, and take it from there. Many claim to be balanced but few do the former, only the latter. That is not skepticism. Also it's important to trust yourself, and look at things with your own eyes, rather than through the eyes of a pre existing dogma. If you can't trust yourself, you won't be able to trust anyone else.
