yes you are being very impatient! don't feel bad though most people are. i know i am, i was thinking about giving up a new practice due to fruitlessness and had to remind myself it had only been three days of practice lol!

keep them wherever you want, like the other guy said, as long as you can access them it doesn't matter. paper can help make it easier to go back and put notes or circle dream signs and things like that so keep that in mind. but again if you can do this on your phone then it's the same thing. most of all take your time and relax into a habitual practice. get it to become second nature to record your dreams and practice a lucid dreaming technique. before you know it you'll be having them. don't give up!
