I know that for me, I enjoy getting to put the spotlight on my students. I also like haveing concerts for my students to be able to demonstrate their skills for their friends and family. I also can work with students of any age, starting at about age 5 through age 100+. My experiences with teaching children gives me the ability to teach even very young students.
If you just want to learn a few chords to strum along to some songs, then learning to play the guitar really isn't that hard for most people. Many students are able to learn a few chords and get a decent strumming pattern going after a few weeks. If you've had prior experience playing an instrument, you can expect to pick it up after just a few lessons.
You do not need long fingernails to play guitar. In fact, it's best to keep your fingernails short! As for the callouses, these may be unavoidable. If you would like to avoid them as much as possible, ask your guitar instructor about lowering the action of your guitar (the action is the distance between your strings and your frets) so that the frets are easier to press down on.
Practice playing individual notes. Holding down a string and producing a decent sound can sometimes be more challenging than it looks. If you don't hold down a string hard enough, you'll get a muted note and if you hold down the string too close to the fret your guitar will buzz. Practice picking in an up and down motion on your string with the other hand. Continue doing this until you feel comfortable moving up or down the neck to a different note. Practice playing the notes back and forth until you become comfortable strumming.
I've seen so many guitar lessons where the instructor simply dives right in and begins teaching chords. Unfortunately, that assumes that the student's guitar is already in tune! Guitars are made out of wood, and wood reacts to our environment, be it hot, cold, dry or humid. As such, guitars frequently go out of tune, and they must be tuned to make them sound good. If you begin learning to play guitar on an out of tune guitar, it will not sound good to the ear no matter how hard you try, and as such, it will become discouraging pretty quickly.
