I don’t have an answer to your specific question, but I just want you to know you’re not alone. I’m also quite excitable and love talking not just about technical stuff, but all sorts of things. I’m quick to smile and laugh, and I probably overshare at times (that last one I had to learn to control).

I’ve had the same worry as you at times, but so far I’ve been 15 years into my career as a software engineer and it hasn’t been a problem as far as I know.
