The single most significant problem with a self taught student is, they don't know what they don't know.
If you don't know what you don't know, you also don't know what you should know. And, since self taught students often end up chasing the next bright, shiny thing, they don't tend to have the discipline to actually learn something before they move on to the next thing.
A good lesson plan is one that starts by setting a goal - a goal that is specific, not "be a better guitar player". A goal that keeps you on one road and doesn't allow you to bounce around learning "many styles". Unfortunately, too many of us want what we want and we want it now and we have little patience for when it doesn't come to us quickly and soon.
You should begin learning the basics of "practical music theory for guitarists"; https://www.google.com/search?q=practical+music+theory+for+guitarists&rlz=1CAACAY_enUS754US756&oq=practical+music+theory+for+guitarists&aqs=chrome..69i57.12808j0j1&sourceid=chrome&ie=UTF-8
IMO learning how music is structured is the single most important lesson you can have. Practicing how music's structure is used in any one genre will give you insight into how other forms are similar and different. There are only 12 notes to work with in "Western music" so it's how you learn to emphasize certain aspects of those notes that makes a "style".
Take in only what you can learn in a few weeks and then a few months. A very good lesson plan builds this week's lesson on what you have learned in last week's lesson and the lesson before that and the lesson before that. If you have no structure to your lessons, then you waste a tremendous amount of time. IMO it doesn't hurt to find a very good instructor and get someone to give you the basic bones of a style and to correct the problems you may have taught yourself.
Many players have learned to play by simply playing songs. Unfortunately, that doesn't work for most of us, at least not in a timely manner. IMO songs should be structured to build in difficulty along with your proficiency. Most of us will need some type of lesson plan to get that. Once you have a lesson plan, you need to stick with that plan from beginning to end. Even if you think you know the material, take the lesson again. Instructors say things differently and you learn things in your own particular way. You may just find there's something in a new lesson that will make other things fall into place.
Don't bounce around. You can work on more than one thing at any time, but stick to the forward progress a structured lesson plan offers.
