I started with just a circular saw and a drill (would not now recommend [1]) and bought "handy panels" from the local big box store to make crappy book cases and such. I was very much demonstrating the aesthetic of the School of College-Dorm.
Eventually I got a table saw and started making MAME cabinets, dance pads, etc.
When I eventually started seeking out better quality plywood I began to make things like speaker enclosures (and better looking book cases).
I was getting into woodworking when television was still a thing so Norm Abram's "New Yankee Workshop" on PBS was my inspiration. Not only is a lot of that on YouTube now [2], but so too are hundreds of others uploading videos on woodworking. We live in a rich time when it comes to hobby how-to videos.
I think of YouTube sometimes more as inspiration ... where I want to get to. For example I like Paul Seller's videos [3] where he makes everything more or less with hand tools. Ishitani Furniture [4] is my where I wish I were.
But if videos are not your thing, archive.org is back and their Magazine Rack [5] has plenty of magazines on woodworking. Just look around.
[1] Forget the circular saw unless you're doing hime construction. Opt for an inexpensive "panel saw" instead — and also an 8' sheet of 1-inch-thick insulating foam to put down underneath the wood you'll be cutting on the floor of your basement or driveway.
