I think there actually is a way to organize everything (arbitrary knowledge) with a single tool/method, and am excited about it and want to make it work better for us all to organize knowledge individually and together. I have written about it extensively at http://onemodel.org (where the current take on the idea is available for free download, AGPL), though not all the features are there yet. There is some more info in a comment farther down on this page if you search for "onemodel". It is extremely efficient and effective (physically and mentally, once you learn it -- about everything needed is always on the screen): you can get around really fast.
