I'm 41 and working on my second career shift. I was originally a lawyer and switched to content marketing about two and a half years ago. I'm currently learning HTML, CSS, JavaScript, and (eventually) PHP. @saluki, your comment is terrific. It speaks too many of my challenges at the moment.
I want to update the CSS of a WordPress theme for my wife's blog and I started reading through the theme files today. It seems really complicated and like a mountain to climb.
What I started thinking is that, maybe, the solution is to break the whole project down into smaller chunks and handle them, one at a time. My career change feels pretty similar: one step at a time.
Not being able to play Fortnite on Linux is probably my son's current, great disappointment. :-P
