+    "WhyIChoseIt": "For a little inspiration, a jump start on how to get on with things rather than thinking about doing them. The concept of analysing time logs also fascinates me slightly!",
+    "WhyOthersShouldReadIt": "I don't think they should, there were less practical tips and a more of an element of 'spending time with family' than I expected. Just read my notes instead: https://github.com/iteles/Book-notes/blob/master/I-know-how-she-does-it.md",
+    "WhatILearned": "It's all about attitude (know what actually matters - hint: dirty dishes is not one of these things - and learn to let go) and knowing what you're doing so that when you work you can hit the ground running",
