If the choice of what to learn depend on a years long dependency graph of other obligations, which currently are the increasingly interlinked:
you end up without much choice at all.
The lock-in periods must be much more fluid and shorter term than those, otherwise it makes the almost inevitable pivots to success impossible.
This is something that Ciro Santilli has heard from several people at the end of their undergrad/PhD degrees. Some online mentions:
When I realized the biggest reason to continue my pdh was to be dr helps, that's when decided I should probably leave.

Porn vlog Updated 2025-12-13
This is a porn style defined by Ciro Santilli as:
  • content is designed and owned by the actors
  • full face reveal
  • doing normal vlog things like talking, visiting places, eating, etc., not just fucking
Ciro believes that this is an interesting type of pornography, as it feels more natural and humane than all the horrible trash that comes out of horrendous professional mainstream porn industry.
Yes, it could go down the YouTube/Instagram alley, and lead the vloggers to do things they wouldn't normally do because of the audience. But who is to say that Ciro Santilli doesn't do the same on Stack Overflow to some extent?
That type of porn requires some big courage to make. Or balls if you will. Kudos to those creators, as it is so taboo it could greatly impact their future job prospects.
The travel sex vlog appears to be the most popular way to do it. Presumably the reason being that you would not be able to interact with people in a normal job, so to keep things interesting you need to go to some random places.
Examples:
Simple to state but hard to prove Updated 2025-07-16
One of the most beautiful things in mathematics are theorems of conjectures that are very simple to state and understand (e.g. for K-12, lower undergrad levels), but extremely hard to prove.
This is in contrast to conjectures in certain areas where you'd have to study for a few months just to precisely understand all the definitions and the interest of the problem statement.
