Now that I'm almost in my forties, I realize everything I wrote back then was bullshit. Earnest, but bullshit nonetheless.
I'm much more cynical, but I'm also much more likely to just do what seems right and figure out the rest as I go. I don't read "best practices" or advice articles anymore.
This is not to say that there is nothing to be gained from such sources; just that the likelihood of it being useful or accurate given my particular context is small.
In this, my attitude is much closer to where it was in my teens and childhood, where I just had to figure everything out on my own.
