Any general advice (dos and don'ts) for a 31 year old virgin with no dating experience?

I'm a 31 year old virgin who dedicated my last 13 years to my career. I surpassed my monetary life goals but now I'm a complete idiot at pretty much everything else especially self-confidence and social interactions.

I'm lost, and I don't know how and where to start my journey of getting into a relationship.

Should I try online dating? Hit on my employees? Take up new hobbies? Try new sports?
