Those who are experienced, are the one who can observe the things well. While developing the code, often we see the code how it looks and stuff. Sometime we see when we debug the error or want to improve our code.
Something constantly goes through our mind while programming, developing or designing. Those all are combination of many things including obsevations. In that regard, I ponder sometime, what can be achieved via observation. What model we should focus on ..How observation can be expanded. What is the limit of observation etc..
