Not necessarily true - if you were really passionate about washing dishes, maybe you would have started a dish washing company, organized a dish washing union, or whatever :-P

"Excel at what you do" is not passion. It is admirable to do the current job the best you can, but I think a discontent with the current job has fueled many entrepreneurs.

Quite true. I would argue that loving what one does is necessary to attain excellence. But it certainly is not sufficient.

Excelling in your field gets noticed. It did when I was a d*mn good dishwasher. Had I chosen to, that could easily had been my ticket into a some kind of catering career. I prioritized college, though, so now I'm just a mediocre procrastinator :)

To every rule there's an exception ;-)
