Sales is a position in which a degree is not required. My sister didn't even finish secondary school, she only completed up to year 10. She has excellent people skills though and worked her way up pretty quickly in sales. She is now a regional manager in advertising for Yellow pages making well in excess of $100,000 per year with a company car.
Most professional careers though will require a degree as the bare minimum just to get to the interview stage.

Wow! where do I apply for a sales job that has potential to lead me up to 100k job? Can shy people overcome their shyness and become a salesman? Also what kind of sales job did she have?

He answered your last question already. And are you wanting to do sales in Japan? Then you'll need the degree and fluency in Japanese.

And any commissioned sales job can make you 100k a year. You just have to sell a million or two in merchandise and take your cut.

Did she also start at YellowPages? Give me some sales ideas, I only know of one from the careers page on Comcast because I was interested in being a satellite/cable installer.

Pretty much every company with more than 12 employees that sells something has a sales department.

If you are a people person that is good at talking with strangers and getting them to listen to what you have to say, sales may be your thing. It is kind of something you are born with.

Sometimes I think that if people invested as much time into actual study and acquiring skills as they do into searching for a way to get around doing so - they`d already be halfway there.

what is going on here?

I am native Japanese and a high school dropout. I am a regular employee of a Japanese subsidiary of a major European corporation and currently working as in-house translator. I don’t know if mine is “a respectable job at a company” but at least I am treated equally with other employees with Uni degree in every aspect (pay, promotion etc.).
I was once a rough and delinquent boy from dysfunctional family. I used to believe that I am born different from those salarymen. Anything happens in our lives.:)

If you are a Japanese native and fluent in English, then yes, Anything happens in your life ;)
High school drop outs, or masters graduates, it's all about having a skill others are willing to pay for, and being in the right place to do so.
Bilingual in a 1st world country which specializes in exports and has a freakishly low number of immigrant citizens is like shitting gold every morning lol.

and gratz on the sweet job! :)

How did you learn your spectacular English? What led you to drop out of high school?
