Ask HN: Continue working on Single Language or Explore other things?

I am developer who has worked for about 5 years. I started with java, spring boot and worked for 2.5 years and later shifted to React and JS and wroked for 2.5 years. I can write mobile app also.

Now I am trying to work in the decentralized products like ethereum in rust. I can nearly work on any language but I am not relly good in any single one. I can go through the code base and can start working on them irrespective of the language.

Should I just pick one thing and continue working on it? or Should I keep on experimenting.
