It's been about 9 months for me since I last attempted to LD, or even recall dreams I was having. I was in school, and flustered with many things, but now during summer I've wanted to get back into it. What are some small tips to keep in mind during the day and things I should be doing?

All I can think of would be doing RC's and recording my dreams in my journal. Any other suggestions?
Suggestions for what method(s) I should use if I do not have a very fluid sleeping schedule?
