I want to pose a hypothetical to you.
Suppose you’re an attorney specializing in contract law. How many competitors do you have out there?
And suppose you speak and write fluent Mandarin.
How many now?
Not so many. You’ve radically reduced the pool of candidates someone needing those two skills can hire.
By virtue of possessing that additional language skill, you just made yourself far more appealing to certain prospective clients and cut a whole lot of your would-be competitors out of the running.
I tell young people all the time, if you want to stand out and essentially write your own ticket in life, combine specialties that very few people possess in combination, but that are solely needed in certain niches.
The same goes for your business.
