I guess someone else wrote this then:

I have met plenty of people who do not seem to be able to muster enough
discipline to really learn something that they are interested in.

Then they were not really interested.


This same person also wrote in the same post:

I myself have done a couple of things in my life which I thought
(and professed) I was interested in and realized only later that
this wasn't really the case.
