Why do many people in their thirties and forties have very poor resources and abilities?
They only focus on executing the job. This kind of job is a grassroots position, and it is impossible to have access to good industry resources.
So at this time, talented people will accumulate side jobs.
Even if you just start with taking a private order, writing a book, maintaining self-media, or working part-time on weekends.
