Destroy All Software screencasts by Gary Bernhardt has some great content. Besides the typical CS degree, I felt that these videos were most pivotal in me writing better code.
You can also view a handful of the screencasts for free (no sign in needed). Some of my personal favorites.

Also, if podcasts are more your thing, we just had Gary as a guest on the Bike Shed podcast this week: https://www.bikeshed.fm/269.

I'm not Gary, so the focus is shifted towards areas I have special interests in — namely: the day-to-day of running a software product business as an indie hacker/solopreneur.
