I must point on one thing, take this example most of us, have experienced many times of some smart guy, giving a smart talk in your high school/college, and you walk out and say to your friend "woah, that was a good lecture/speech, that guy was awesome" .. after few days you go on with your normal business, but somewhere inside you, you feel the guilt of not applying, what you learned during that lecture. Well you are not always right, our brain is only as much capable of seeing our own improvement, to a limit, going from 18-25, you see a lot of changes, and you don't see a lot of changes, so the point is, that its not necessary for you to always apply, what you just learned immediately. Yes, try to use it soon, but its not necessary to apply, what you heard from that smart guy, starting tomorrow, because his circumstances are way different than yours, and he would know a lot of contingencies related what he said, of course.
