We are all very strange in terms of how we get used to things, and then move on to other things.
When I was small, we used to play cricket. Almost on every alternate days, if not daily. We used to play in the big grounds, as well as in the small places near our house. We played even at the rooftop (chat, as we used to call it), and had all sorts of weird rules. Then, all of a sudden, after school life ended I never played it. Once in a while we played it during our final year in engineering, and a couple of times in the B-School. But never on a regular basis since my school days.
Another strange habit which comes and goes is the choice of drinks (not liquor, but general drinks). In my engineering days, it was always Ice Tea. We had a lot of small stalls outside the academic complex where we got Ice Tea and Veggie Pattice. So, it was almost always that for me - between and after the classes. During my MBA days, I got used to hot tea (made from tea bags), and even though it tasted real bad the first time, over time I got so used to it that I preferred it over freshly made tea as well. I came to HK for my job, and as there was no tea available, discovered a really nice coffee pack. During my two months in Manila, I got used to Hot Chocolate (as I disliked both the tea and coffee there). The thing is, at different points of time, I developed different hobbies, and then moved out of it as soon as my surroundings changed.
Currently am on a 3 months leave, and am now getting used to it as well. In my first job, I was used to working long hours, first to come to office, and last to leave. In my last job, I was never in office for long times, and was always moving around. I had never imagined what life would be when you do not go to office, and have full time to your self. Or how it would be to spend you time deciding on which movies or serials to watch next. As days pass, I got used to it as well. May be, this is the longest break I may get for a good part of my working life. All my life, I always woke up early in the mornings - and now its never before 10 AM these days. And am sure when I re-start my job, I would be back to the schedule of getting up at 6 AM.
