Tips For Networking?

Potentially a dumb question, but what’s the most effective way to reach out for networking and coffee chats?

I’m starting an MS in Finance program this fall and want to get ahead of recruiting by building connections early. Is it as simple as sending a high volume of LinkedIn messages, or is there a more targeted approach that works better?

I tend to overthink this kind of thing, so I figured I’d ask for advice here.

Thanks in advance.
