Nicholas Felton is an information design pro. For the past few years he has logged basically everything he does on a daily basis and then compiles all of this information into an annual report.

Check out the Feltron Annual reports and his other work on his website: http://feltron.com/
Felton now works at Facebook where he inspired their new(ish) timeline feature (I think).
Also, this podcast is really interesting in general, but I recommend at least listening to this episode bout the Feltron Annual report:
