cooking up ideas, solutions, plans, trying to figure out the answer to some question that pops in my mind or trying to figure out the reason behind some obscure thing or pattern that may have caught my attention, reading articles or watching some good videos online. (Talking about videos, whoever put up that link to Randy Pausch's Last Lecture Video on HN, just completed watching it- THANK YOU VERY MUCH, tried, but its been tough to trace back to the original posting) Driving, lots of driving on the country side, love the changing scenery, that's one thing where I can continue the thinking while doing something relaxing. (edit: about the driving, its big time fun, to go into some obscure parts of a city or new neighborhoods (obviously when the traffic is real low - like late in nights), or some new places in the country side, figure out new routes to the same places, its like a jig-saw puzzle. Another thing I am addicted to - I like seeing the same places in different circumstances, seeing the same neighborhoods in the day, evenings and night, or some remote places in the country side in different seasons - its great fun/relaxing and somehow I feel my mind getting stimulated at the same time)
