The key here is: know your audience. What's impressive to a SV tech entrepreneur is often incomprehensible, absurd, or simply farcical to someone like a PhD in Classical Philology, or a tradesman that owns his own small business. And vice versa - achievement doesn't have a universal definition. This becomes really obvious when you compare different countries, say, the U.S. and France, for example.

Figure out how your audience defines achievement and work backwards from there.
