I'm in that age bracket (30-50), and trying to transition from tech-support/helpdesk into something like coding/linux-admin/devops/etc, anything that would pay enough to allow raising a family in/near a major US city.
I find it daxx hard to even get a phone call back because of my age.
I spend a lot of time learning this and that and have s small portfolio that can be viewed. But still no joy.
So I keep on pressing myself to learn new skills, putting in 10-30 hrs a week, ON top of my 9-5 job. I did not I work this hard with this much focus in college. Honestly much regrets.
