Ask HN: How many times do you lose track while programming? And how to avoid?

[xenonysf]

So I find myself, "what I was doing", "What is the next step now", kind of situations. I am doing this and that, and suddenly something distracts me and when I am done with that distraction, I am like; "hmm what I was doing"? Sometimes it happens often. How do you keep track where you were?
