Lesson 1 Answering questions can be really frustrating, especially if you see that someone tends to ask questions only because they have developed a habit of not thinking for themselves. If you want to help them, tell them this in a way that will give them more confidence in their ability to think for themselves "you are a bright person, just have a bit of patience and you will be able to find this type of answer for yourself".
Lesson 2 If you have no patience to answer peoples questions, have the courage to admit it. Don’t make other people suffer because of your own inpatients. Be straight up "i really should tell you the truth, I’m not up to it now, please consult someone else".
