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.
