The job interview. Usually no way to get filthy rich, but we all have experienced it.
I want to add something about “political correctness.” In some jobs (marketing for example) you may get questions where it is tempting to give the boring political correct answer. If you have strong opinions on a matter I would not like to keep those opinions down. Explain your position, even if you may be a minority.
Honest people stand out, there is enough of bland people out there.
