Enthusiasm is learned.
Had a big heart to heart with a college professor right before graduating, about how I don’t know what I want to do or what my “dream career” is.
Her response: nobody does. Those people who say they do, don’t. Find a job, you’ll learn you become passionate about it whatever it is you’re doing.
Of the three people who graduated that semester with physics degrees, I’m the only one who’s ended up with a decent job in my field out of college. I found an imperfect job and learned to be passionate about it. They call me lucky but I know the truth.
