finished what i usually do in one day in 1 hr and 45 mins when these conditions are met:
1) no one is in the room except for me
2) the aircon is on
3) i can move around the room to do my work (spreading out my stuff over 2 tables)
4) i don't have to type in the records in the excel file i've created for the purpose of tracking.

the disadvantages:
1) i'd still have to type in the records tmr :(

i feel so much more fruitful in this 1 hr and 45 mins than my hours in the morning!
