I joined a compiler team out of college because it seemed like fun and I'd never worked on compilers before.

I went from C# to embedded engineering and reading clock and wiring diagrams because there was a job that needed doing and I was the one there at the time.

I went from embedded programming to running my own startup based on Javascript and React (technologies I'd never used) because I had an idea I wanted to share with the world.

Just go out and try to do things, you may be surprised with what you are capable of!
