This is, perhaps the worst piece of advice in American history.
I'd love to work with Dolphins at Sea World. The idea of getting up every day and working with them, teaching them tricks, playing with them and socializing with wild dolphins (before they are trained) sounds like an amazing job. Heck, even going on archaeological digs sounds like a hoot. Acting in a Broadway play could be a lot of fun too.
Unfortunately, I also know that a lot of other people think this way, and that these job doesn't pay beans - unless you are the 0.0001% and hit the "Big Time". So, I got my degree in Engineering; and when I retire, perhaps I'll get that dream job. In the meanwhile, I have a job that provides a comfortable living.
Loving what you do is important, but it must also be tempered with a good dose of 'reality'. Choose a career that you like, that you can do well - and when you have reached your level of success, then you can do whatever the heck you want to do. The first task, is earn enough that you are not a burden on your parents, or society.
“Find out what you love and do it,” because that’s passion
This is, perhaps the worst piece of advice in American history.
I would say a better way to phrase it would be to say “Figure out something that you love and find a way to get paid for it!”
That's called a hobby, not a career. Rush got lucky and is in the .00001%. His experience is NOT the norm.
I wanted to research history and dig up sites. Found out I would not be able to do that and live, so I became an engineer and do those things on my free time.
