A few random thoughts:
- Willpower - is it a depletable resource? Or maybe it isn't? The article suggests it's probably a dead end. Based on my small experiments with diet changes, changing habits in my case requires environment control, self-education, self-awareness and planning. No moment-to-moment willpower necessary, and in fact if it comes down to that, I usually fail and eat that delicious but unhealthy treat/cookie/pizza.
- I've bought & tried a glucometer. Very cool device, allows you to test actual effects of food on your blood sugar. It's amazing to be able to perform an actual blood test yourself, at home, within less than a minute, using a device that costs around $20. Brilliant.
- I'm experimenting with eating food which has low glycemic index, and seeing how this affects my moment-to-moment energy level, focus, emotions and optimism. So far the results are very encouraging. If you don't know what it is, and you'd like to have more energy and focus on a typical workday, I recommend learning more about glycemic index.
- There is a phenomenon I'd call "learning too fast". I've concluded that I was reading too many books, and analyzing various areas of my work and life too much, without acting. The way I evaluate it is by looking at the ratio of applied knowledge (change in a way I do things) to acquired knowledge (instructions on how to do things differently, taken from books, friends etc.). This ratio is appallingly low for me. I'd say that I apply maybe 5-10% of what I read in the last year, and that only includes advice that I decided to be meaningful and worthwhile. Rate of knowledge application is just as important as rate of knowledge acquisition. They don't need to be equal, but learning too fast compared to applying what you learn may lead to frustration ("I learned so much, but there are no improvements in my daily work/life") and is just waste if you dedicate lots of resources to it.
