Practicing will not do any good, if there is a lack of interest. You need interest to be excided about it and have intent. Without it, there will be no LD. Writing in DJ helps with dream recall. Try to tell him your adventures in LDs, or have him read some DJs here on DV, that may make him interested. Otherwise, keep in touch here on DV to keep your motivation up. Good luck, it's good to have a friend interested in same thing, but you can't make him like it. Just know, you have friends here you can turn to.
