just believe. you are an expert lucid dreamer, you just have you have the intent that everything will work out the way you want it, and it will that goes for other things in life too

start with a journal by your bed, and a pen so you can write down any dreams
question reality currently throughout the day, spontaneously
do reality checks spontaneously and at odd occurrences
believe you will
say some mantras before bed
get plenty of sleep
don't give up

you will have a lucid dream soon
