"I must admit to feeling some hesitation before writing this post, as I fear it may come across as self-indulgent. My motivation in writing it was to communicate how useful self quantification can be. It is a lifestyle change that I believe some can benefit from, and one that can reduce the chronic stress from which far too many of us suffer."

It seems more interesting than useful. Lots of analysis, not much benefit. Maybe

"The only hard targets I currently have is to spend >10% of time writing, and >15% of time reading, which I have hit. This was something I struggled with tremendously before, and I only succeeded when I started tracking work type specifically."

is a benefit, but it's fairly representative in that it's something of a goal within the system rather than an external benefit.

Perhaps there's guilt relieved by realising that a tedious week spent organising a mentoring group increased the amount of interaction as a mentor, but what are the benefits beyond that?
