During the day, I forecast sales at supermarkets, drugstores, furniture, perfume and other retailers and calculate order proposals. Lots of time series, with an emphasis on fast, automatic and robust data cleansing and forecasting - with some logistical optimization thrown in for good measure. I'm active in the International Institute of Forecasters and an Associate Editor for their practitioner-oriented journal Foresight.

At night, I switch hats and do inferential statistics for clinical and biological psychology.

I'm never bored. And I use R.

comment What are some critiques of David Allen's GTD system?
It has been proposed to close this as opinion-based ("answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.") I disagree and voted to leave open. The OP specifically asks for references.

comment How to handle disturbances to “don't-break-the-chain”?
For "do X for Y minutes per day" type tasks, I allow myself to retroactively cross off a skipped day if on a later day I do 2*Y minutes. Yes, it's cheating, but it actually motivates me to catch up on what I skipped/missed!

comment How to maintain concentration after 7 hours
YMMV, but I know that if I get only 6.5 hours of sleep, I will also be tired, sensitive to light and unable to concentrate after seven hours' work the next day, usually earlier. My first suggestion would be to try eight hours of sleep for two weeks and see whether this helps.

comment The routine of the successful German?
I am German. As it is, this question seems far too broad - the secrets of productive Germans are likely no different than those of successful Americans or Fijians. You'll find healthy, fit, smart, sporty, studious people all over the world. Please consider editing your question to be more specific. As it is, I voted to close.

comment Does military background enhance productivity?
Even with conscription, there typically is the possibility of conscientious objection, and so we are back to the question of whether less disciplined, less hardworking etc. conscripts disproportionately make use of this possibility. (I'll stop now before I'm accused of perpetuating stereotypes.)

comment Does military background enhance productivity?
Nice question. There may also be a bit of selection bias here: does military service make you more disciplined, hardworking etc., or are disciplined, hardworking etc. people more likely to sign up for the military in the first place? (Assuming that there is a correlation in the first place.)

comment How do I set aside time for leisurely reading?
Nice answer, +1, especially for If you successfully transformed this into a reading space, you would then struggle with sleeping. You don't want to associate lying in bed with reading, because that will mess up falling asleep. I would definitely recommend finding a chair to read in.

comment Trying to be an early raiser
Don't expect to be able to change sleeping patterns within a few days. Your body has gotten used to a particular sleep/wake and REM sleep pattern, and this will be as hard to change as breaking an addiction to nicotine or caffeine. That said, I suggest pushing your wake-up time back gradually, e.g., by 15 minutes each day. This gives your body time to adjust. Make sure you go to bed early enough, and cut back on the caffeine while you are making the transition.
