>>1317293I'd start by figuring out how to catch bluegill or other baitfish near your area.
>>1317332 has some good advice for that.
there are basically two aspects of learning to fish: 1. technical/gear related stuff, like how to choose the right rod/reel for the fish you're targeting, how to tie knots (learn the palomar, improved clinch knot, and arbor knot to start), different baits/lures, etc.
2. How to actually locate and catch the fish. I've found that if you can find where bluegill/other bait fish are located, generally speaking you're also going to find other fish in the vicinity because a lot of fish like bass or catfish eat those baitfish as a part of their diet. So if you can get decent at locating and catching those fish, it should be straightforward to progress to other species.
That being said, if you have an interest in bass or catfish or carp, you may just want to dive right in and buy a good entry-level rod/reel for that species, and also buy an affordable lightweight rod/reel like a $20 Shakespeare combo for going after bluegill and baitfish.
