Either:
1. Become the best at one specific thing OR
2. Become very good (top 25%) at two or more things.
That might sound simplistic or defeat the whole notion of being a ‘specialist’ to get ahead. Yes, career-wise, being a jack of all trades doesn’t make you indispensable – but only if you’re mediocre at all the many things you ‘know’.
You can do technical writing – but is it good technical writing or creative massaging of copy-and-pasted text? You can speak a few languages but can you converse in them or only know how to order specific dishes (I plead guilty to that when it comes to Cantonese)?
I can do a lot of things – but I don’t claim to do them all well. So I can write and have the potential to do better (that’s why it’s an awesome skill to have if you even have a smidgen of talent). But what else is there?
Sadly, I don’t think scaring PR n00bs on the phone is a marketable skill. I will go back and attempt to pick up one of the essential skills for world domination.
