I would say the question asking is the same as tarot and all divination. Avoid yes / no answers to questions (too simplistic and binary). Make them open ended and positive.
for example....
will I ever marry? too open, too binary
will I be lonely forever? negatively worded, binary, too open.
what do I need to know about the chances of meeting someone in the next year? much better! getting to the point of the question and giving a specific time frame.
what do I need to know.....? is a good way of taking topics you struggle to write out a details question about. I have also had success with Lenormand asking about general topics "this month" "love" "work" etc. But specific is good too.
Some years ago, someone compiled a question thread here of great example questions that work great with tarot. I think it's worth trying them with lenormand as well. That thread is
