After you identify a personality trait of yours that you don't like, it is not healthy to just accept it as it is. You can always improve. Choose better, invest less time in every try and spread it longer, or... Change your mindset! You don't really need to stick with all of your curious learnings, but of course, we have to stick with some otherwise you are just wasting time.
As long as it doesn't impact your life too badly, why would you change something.
About your feeling of failing I had this too. Once I told my therapist I feel like I have this huge debt of all the never finished projects and starting something new would increase the debt. My salvation was allowing myself to "fail" and experience the anxiety and guilt coming with this. Turns out this feeling of failing was not good for anything and more like a story in my head.
The school of therapy which turned my life hugely around was Acceptance and Commitment Therapy just if you are curious and need another hyperfocus topic.
Also if you already know the term hyperfocus you already read about ADHD. My medication make a huge difference to get going despite frustrations.
Don't be. That way lies misery for you and those around you.

"Focus on specifics" ... don't have a problem with this but sometimes the pace is very fast and then after it, I feel depressed
"Make daily plans—and work on sticking to them" and "Use reminders" ... yeah I will give it a try
"Stay social" ... Have to say that I am feeling very good when I am alone. But maybe it's not so good for me. I will try to become more social in the future. My wife will support this ;)
