I used to always get excited over new tools, but stopped because if they don't solve a type of problem I must or want to solve, it's just not that interesting.

I used to always get excited over new tools, but stopped because if they don't solve a type of problem I must or want to solve, it's just not that interesting. Algorithms, data structures, design decisions and methods (with their limitations), business domains I develop towards, and choosing what to solve end up be more interesting. I started to look at Rust, for example, for at most a few days, but I am not solving anything that needs it at the moment, but can understand why it exists at least. But, if you can use something new and shiny, great. I rarely had that opportunity myself.
