dearest ‘well-meaning’ project manager: every time you ask me a question about something unrelated, the time for me to deliver this feature increases by 30 minutes.

please choose your questions wisely, consider:
1. am i the right person to ask?
2. could someone else answer this question?
3. do you need an answer immediately?
4. is the answer to this question more important than completion of the feature i’m working on?
5. could this be done asynchronously e.g. via email?
