I tell my students at the beginning of each term, I am not a super lecturer to let you understand every word in my lecture, and you are not a super student to understand and follow every word. So do not hesitate to interrupt me any time during the lecture and ask me any question. I am here to teach you and you are here to learn.
Don't follow the easy path. It's very crowded and you'll end up in the land of mediocrity. I took every course offered at the master's level in the college of engineering before starting on my doctorate. I took more math courses than the math majors. I've never regretted any of it. At work I gladly took on the hard projects that others avoided. My first boss right out of grad school (Dr. William R. Waldrop) was an inspiration and example. Back in the days of mainframe computers and punch cards, when Lockheed couldn't deliver a 3D transient model of the Saturn V booster to NASA as promised, Bill Waldrop said, "I'll do it!" and he did! Together we tackled many problems that supposedly couldn't be done. It's never been boring.
Stay creative, do things yourself, that's your lifelong path you're after, not superficial rewards which academics or business managers get on a short-term yearly basis.
Have fun, drop what you are not enjoying or which you can't do well, focus on where you are and feel best
Notice the difference between an INSTRUCTOR and a Material Presenter.
The instructor gives you information, peels a layer off of the onion, and gives you additional information, and then lets you ask questions (until reaching a layer of the onion that is beyond his background). A Material Presenter can only repeat the "bullets on the power-point chart", and cannot provide relevant additional details on the subject matter. Get the most you can from an INSTRUCTOR. Jan 8 2020
