My enormous blind spot is that I then miss legitimate trends, and I can completely fall behind in the industry.
I also find myself not learning new tricks and techniques that would improve my workflow, and have to take time out of my schedule sometimes just to play around with new approaches.
I can definitely see how both approaches lend something, and both approaches have huge weaknesses.
The biggest issue that I've actually seen with novelty-seekers it that they'll build something based on some new framework or tool--that turns out to be be really rough and they hit those rough edges and get frustrated. Then instead of trying to fix the tool they're using they move on to some other new shiny tool of the day. That behavior can leave a ton of tech debt in its wake.
As you mentioned I do really have 'ton of tech debt'. I hope I could change my behavior and reduce my tech debt.
Sure, as long as the quiz doesn't involve how to use something in ways not spelled out in its README. Or issues and limitations in applying it --- also not in the README which is more of brochure from a fanboy perspective.
In other words, don't ask, "How did you use that to solve a similar problem? What problems did you encounter, and what were the solutions and workarounds? Would you use that again?"
Someone who knows about alternatives isn't nearly as useful as someone who has the inside knowledge to evaluate them in a relevant way (that is bang on).
I wouldn't want you to change, just to find your place in the world and satisfaction in being naturally you. Its like you have pockets full of keys and really good at finding new keys just no locks to use them with. There are other people who have the opposite problem and have locks they obsess over but find looking for keys exhausting, frustrating and confusing. You can be a force multiplier for them.
One idea, if you wrote a blog about each new thing you try, you accidentally create something "you stick with" because its about all the things you are not sticking with :) When your attention moves on, its not a failure any more because each article is a success. Documenting what you are doing might also let you spot some patterns that take you to the next level.
I wonder if you might find teaching \ training a rewarding occupation. Keeping up with continually moving tech and having a breadth of knowledge might make you excellent at that.
