Nice job, thanks.

Couple of nitpicks:

suggesting that a tendency to deliberately choose one's work tasks may help procrastination/akrasia, and does harm it.
There may be a typo in here somewhere.

I find that numbers in a table are easier to read when aligned around a decimal point. The same effect makes it harder to interpret .26 right below .3 when skimming. I suggest using the same number of digits and writing .30 there.
