Interrupting
Imagine a situation: you have the most brightest idea you’ve got in last ..hm…month. So you start working on that, analysing, sketching, collecting references. Later you start writing, diving in the waves of knowledge out there, digging for details. And now, there comes something totally different, not-exactly-exciting, equipped with a deadline so it requires action. A plain old good manual work. You must hold back you brightest ideas, just spend the damned manual efforts.
What do you do in those situations? How to not loose the context and thread?
