I wish I knew before that having daily and weekly (and monthly etc) lists is okay with GTD! I somehow thought it was not true GTD and tried to do with contexts only, didn't work for me! (had too many NAs and projects/maybe projects and got lost in them..)
I'm still learning - having tasks on context lists and daily list seems a great idea, not to repeat stuff indeed - might try that!
It's also important to treat lists as 'guidelines' and 'preferred action' and not obsess too much about them (I sometimes lost them and only then remembered to do stuff and felt sort of guilty about it!)
It's still actually best to be accountable to someone to actually do stuff
