Wasted Time Re-Researching
I found an Ancestry Quick Tip titled Wasted Re-research Time. This quick tip by Earlene Scott is to remind others to document all their resources and what was found. Even if you don't find any information, just make a note that you've already checked that source so you don't end up checking it over and over and finding nothing. I have gone back to the same Census Record many times before because I didn't make a note of what I found there, so I am slowly working on following Earlene's advice.
Ancestry.com's editor then made a note at the end of this Quick Tip that said that Ancestry.com's Charts & Forms area includes a research calendar to help you record all your sources and information. I was not aware of this, so I downloaded it and it looks like this. It could be a helpful way to keep track of your research.
