Do you take notes on almost everything? How extensive are they usually?
I've always felt like it's too time consuming to take notes (especially in my own words) but also recognize the likely increased retention advantage from doing this.
For instance I just finished reading a Brennan Dunn's book "Double your freelancing rate" and published the summary in here: http://blog.nimblegecko.com/notes-on-double-your-freelancing...
Or here are the notes on second week of Coursera "how to reason and argue" course - https://www.evernote.com/shard/s42/sh/cf6b1dd3-51aa-4bc0-b94...
Hopefully it gives you an idea on how extensive that is.
2. After I finished writing down the note, I copy its contents into a separate note in Evernote and delete everything that I cannot turn into an actionable item.
For each actionable item I add a tickbox (Cmd-Shift-T).
3. Then I estimate how long it's going to take to execute on that item and add a ticket into PivotalTracker. I normally try to group tickets by epics (product, marketing, consulting etc).
Hope it helps.
