Stay in sales, you can move up to run a sales dept if you want then become CEO, esp if you like start-ups. Nothing limiting a very strong sales rep. You’ll probably make more $. If you’re very good at sales, you’ll likely make more than avereage corporate lawyer. Several folks I’ve worked with and learned from have gone this route, 3 have ultimately become CEO’s of SMB company. As you progress, you’ll learn contracts law a bit anyway.
Don’t recommend learning Chinese unless you are really, really in love with it & committed to working very hard and very long hours for a long time with large sacrifices. Chinese is very hard to learn and it’s not just language – there is culture, way of thinking, living and many years of developing contacts and trusting relationships before you will even come close to an even field with others who were born & brought up 1/2 & 1/2. Northern Asia is much different from doing business in NA, SA or EMEA, and “China” has many different regions each with different languages, cultures, etc which are all in turn much different from JP & KR. You need to really want to “go native” and jump in for a few decades, or forget it. It ain’t like a gringo living in SA for a bunch of yrs, learning language, culture and making contacts and then off you go doing business. It’s harder/takes longer.
