Galileo had wisely said that One can never teach a person anything, but can only help them find it within themselves. I believe in helping people realize that they are capable of anything they wish to

Simply frank. Exemplary in his endeavours. Always accomodative and caring

A genius is what I would call this person. And most importantly, he would never give "I don't know" for an answer. He's not afraid of learning and exploring new perspectives. He has an open mind and will always make time to explain even tiny trivial details. He does not expect students to keep up to his pace and is patient enough to repeat explanations until the last one understands. He also knows a bit about how human brain works so he can tell if one has really understood or not. And he has an extensive general knowledge and has a knack of putting the dots together in the most unique and experimental ways. I have personally witnessed him putting his students first when he himself had deadlines to deal with. He will be worth every second of yours.
