Do you question your own code shortly after you wrote it?

Do you question your code shortly after you wrote it? I find myself questioning everything I have written weeks, even days after I have written it! I often contemplate rewriting everything. I wonder if this is normal behaviour or if I am just too worried about my code being shit instead of continuing on with projects before I just get worried and start everything over?

Though, I don't know why I should care. Nothing I've published has ever broken a hundred downloads (excluding Android's Chinese pirates).
