I want help tracking down two discourses.
First discourse is where The Buddha is asked how long it takes to complete his training and he answers posing a counter question, then lists an amount of flawed qualities in a learner. It ends with him saying that if a disciple is of good quality the teaching can be reslized in 7 years... or in a day or so (this part similar to satipatthana sutta). I think this one is in the Anguttara Nikaya.
The second discourse i've heard claimed to list factors which lead to success in one's pursuit and the two;
- Thinking about the thing one is developing
- surrounding oneself with people who are into it
are included in that list iirc.
