networking

I will be moving into a new house in a few weeks. It's an older house (built in the 60s) and hasn't had much updates in terms of wiring. I want to be able to run a hardwire cable to each bedroom to maximize my Internet performance. My wife works from home and I'm hybrid, so I want to ensure we're not just flying on WiFi.

Are there any resources or how tos that can give me some information on where to start? What to look for? What to do first?

I'm struggling with figuring out what I should try to tackle. Should I just run an Ethernet line to the room that's an office and start there? Or is there some well thought out approach I can make?

I know this is probably vague, but any assistance would be appreciated.
