The worksheets are mostly based on highly recommended books for productivity. Like GTD, Principles, ONE Thing, OTT and many others.
I fill out the worksheets by hand. I archive the majority of the completed worksheets. And information that needs to be searchable gets transcribed into accompanying spreadsheets or documents.
The worksheets have been critical for maintaining my current projects without wasting time. They are great at helping me maintain strategies I've worked hard to acquire. They can also help teach these strategies.
I've been considering publishing these worksheets as I have dozens of them.
What would make you interested in using worksheets?
