Well, unlike certain other instruments, there is fingertip pain involved in learning to play the guitar. So learning does require enduring that discomfort until callouses gradually develop to protect the fingertips. Unfortunately, some cheap guitars might cause more fingertip pain than necessary because the distance of the strings from the fingerboard, or the action, is far too high, and so they demand more pressure in order to produce clear notes as opposed to a muffled sound.I remember one year I was loaned a guitar to take home to learn. Never had the patience for it.
I really wish I had learnt to play.
Even today, I would love to play the guitar.
Maybe I will learn when I retire
So getting the right guitar is essential in preventing discouragement due pain that might seem unbearable. Also, fingertip callouses thin considerably with aging and don't seem to develop as quickly nor as thickly. In that case, playing a guitar with nylon or plastic strings, as opposed to steel or copper, will help.
