In order to be unique in a professional career, you need to be in the top 1% of what you’re doing. But reality is, it’s hard to be in the top 1%. Your chances are near null, unless you started doing it early, have good mentors, and a bit lucky.
Scott Adams suggests another thing instead, and I completely agree with him. Instead of trying to be in the top 1% in a field. Try to be in the top 25% in three or more fields. And make sure one of them is related to communication: public speaking, writing, etc.
You now communicate well, know 2 or more skills, and you’re pretty good at them. You’re now unique.
