Coding Rythm 
writing code is usually very creative work. However, sometimes its just boring standard lines you have to write down to get something running. In the middle between being extremely creative and the boring stuff lies something that speeds up the development. I found that I can get into the Flow when doing things that do not require absolute concentration but some distance from reality. Its that point where the world around you slows down and you can just watch the code flowing from your fingers including errors you know you are going to type and correct before they appear on screen.
In earlier days I used to listen to music much more often while working than today. However, it usually helped me shut off what's going on around me. And I remember that I entered the flow more often too. It starts with coding at the same speed the music has. Best results I had with the already talked about "
Boxhamsters" who play quite speedy sometimes. Knowing the music well helps a lot, but I guess for whoever wants to enter that state can use whatever helps to concentrate.
I guess I will take my headphones to my new office in Seoul.
