i was wondering, im hearing people like " i ld’d ONce this month ".
are they just saying that because they werent trying or it didnt work. 
Both is possible, but for most on this forum, they tried and it didnt work (happens even to me still too many times… 
)
Depends on the person. I can’t. I’ve gotten just over 20 nights with ld’s in a month. That’s my record. It hovers around 15 out of 30 nights a month for me.
There are some people in the Competition thread who do every night though.
Could bee a little of both depending on the person. Could also be because they are new and do not have as much experience. As people have more lucid dreams they become easier.
Anyway to answer your question, yes it is possible to lucid dream every night.
Go look at Freecube’s sig, the “i can ld at will!” topic, and the “questions and answers” topic.
