Take A Moment To Stop Gathering

For those times when locating information seems easy, stop and take time to analyze what you have already located. This is particularly good advice if you're searching on a collateral family in hopes of learning more about the direct line. 

Get off the websites, get off the internet, email, stop gathering more information, etc. and look at what you have. Sketch out relationships, make chronologies, make timelines, etc. 

You may see errors you didn't see before or opportunities you have overlooked. Either way, you're better off! Sometimes it pays to stop collecting for a while and do some analyzing.
