I've been playing guitar on and off for 5 years, and I'm 23 as well. A teacher is only good for these reasons.
1)you aren't motivated to doing anything by yourself
2)you are at a point you feel can not be passed(which you can pass)
3) you are trying to Learn theory/a song in the quickest/most efficient way possible.
4)somebody to critique you on form/feel/ and other things that normal lly would take you a while to figure out/develop if at all.
Before you get a teacher ask yourself... What is it that you really want to learn?
90% of anything you want to learn is possible online.
There are ear training programs/tabs/even lessons.
My suggestion is to go to lick library.com (or Google it) and learn some of the songs on there.
They have some intermediate songs, and then songs I like such as...
For the love of God,Tender surrender...etc
There are some really good players teaching you advanced songs there.
But again, just ask yourself what it is you actually want to learn.
And if you have the discipline to actually learn it on your own Google is a very powerful tool.
You can also ask me anything on here if u have any questions.
I'm not the most knowledge able, but I was a guitar nerd for 2 years and have about 50+full pages of theory/licks/ideas/chords written out so I'm sure
I can be of some help.
Either way good luck on your journey!
Edit: the breakthrough song to learn on guitar is Canon Rock. It will take you to the next level.
