Wikipedia:Best not Perfect

What I don't like about the way most Wikipedians talk is how they act like how Wikipedia should be perfect. We are only using the information we have about the subject we may be talking about on Wikipedia.

But shouldn't we at least try to be perfect?
Yes we should, but don't act like you have to get to it perfect, just try your best. No one is perfect, like someone could make a vandal and not know it is a vandal.

It could be argued that acting like you have to be perfect enforces this unofficial rule. It is kinda true, however, you got to know that you can't ever be perfect. Even if you make a major flaw you shouldn't panic.
