You want advice from someone who has done similar work, but your message asks them to explain everything they know. It is difficult for them to see where to begin.
Describe the situation briefly and name the decision you face. Include what you have already checked and the constraint that matters. Ask one or a few related questions, leaving room for them to decline.
Distinguish experience from certainty
Ask what conditions shaped their answer. Their situation may differ from yours in ways that change what is useful. For consequential financial, medical or legal decisions, seek appropriate professional advice rather than treating an informal account as sufficient.
Thank them and use the response deliberately. You can ask a narrow follow-up if something is unclear, without assuming an ongoing mentoring arrangement. Keep notes with the decision and check any factual claim that you need to rely on. An experienced person's perspective can help you see an option, while the final choice still needs to fit your own circumstances.
