nah, just watch his tutorials, collect questions that you want to ask him, maybe a coin or two that you would like to analyze and get his feedback on. thats what i did and it was a great experience. do the work, share your screen, let him give feedback.

just imagine youre a teacher, how woud you like your student to be?

also, dont be afraid to ask questions. people tend to be passive. if youre not rude about it you can ask a question nicely, even if he is talking about something you might not be as interested in/you already feel comfortable using that skill. :) let him help you by showing him where you need help.

haejin, you the best. thank you.
