Wikipedia:Don't make perfect the enemy of better

Sometimes on Wikipedia, you will try to fix a problem in an article and encounter resistance along these lines: "Why should we change this article when hundreds of other articles have the same problem? Why don't you fix those articles before you ruin this one?"

The argument is never valid. Our goal is always to improve the encyclopedia (cf. WP:DE); that project is not helped—in fact it's hindered—by the suggestion that editors must fix every instance of a given problem before they can fix any instance of it.

Remember, there is no deadline. We can fix problems with other articles later.
