If you're a 20-something feeling down because of the Forbes 30 under 30 list drop today, it's mostly an anti-signal. 

The legit people are legit because people already know the company / product / work and the ones you've never heard of until the list, well, they mostly fall off the map in your 30s.

the biggest red flag for this list in my country is that it appears in "the most prestigious newspaper" and it is a 50 page booklet "on innovation" and the only thing that you see in there are old people on pictures with young people.
