I'm a programmer and my work requires intense mental focus.
My goal is to get 8 clean, productive hours of programming per day.
I tried this yesterday, and I managed to get only 2:35 hours of clean focus.
As stimulants, I used:
a) coffee (2 cups) b) aerobic exercise (30 minutes)
I don't want to abuse coffee; because the effects I get after 2 cups of coffee are the opposite of what I want (dumbness / jitters / inability to sleep).
Aerobic is really good; but the good after effects tend to last for a short time. I exercise for 30 minutes, feel a great focus for about 45 minutes to 1hour~ after it, and then I have to eat which again brings me 'down' to a lethargic state of mind.
My personal guess is that diet is the source of all my concentration problems. I was thinking of buying alots of fresh fruits and then combining them with a bit of coffee to break that 8 hour barrier.
My question is: how do you get yourself to focus? Are there any other stimulants beside coffee/exercise that are great, and I'm missing them?
I personally can't focus unless I get an external stimulant. My diet consists of mostly processed foods / coffee / aerobic exercise. And this worries me.
