Bill my first guitar when was 13 was a steel string and after a few months I sold it and then bought my first classical guitar. I played it and read books and changed to my left leg and taught myself how to do a Travis pick with my thumb and two fingers. This got me hooked. So a year or so later I found a guy , though the local music store, who played true classical music and he agreed to give my lessons. First I learned how to read music really well, and then had to forget everything I had taught myself. I took lessons from him for two years and at my first recital I play Moonlight Sonata and Prelude to Opt5. After that that teacher said he could not teach me more than I had learned and there was a classical guitar teacher at my recital and he talked with with me and said he could take me to a farther in playing. He lived an hour away and I took lessons from him for two more years until he said I was at a level that if I kept working he would , be available if I wanted to talk and said I had advanced beyond him. So my earlier bad habits had been gone.
So thinking about Chordie members, there are some who have steel string guitars and also a classical for the sound. There is nothing wrong with that. Not every person who buys a classical guitar wants to play different songs than they normally play.
Bill I made my living in the corporate world and still played every night for at least two hours. I retired early and put in more and more time playing and doing concerts. Later I began to teaching classical guitar too. Those who worked hard did really well and 3 who got full music scholarships. Others dropped off because they were not dedicated enough.
As far as current bad habits , I hope they ended many years ago. So for the last many years I do not think I have any bad habits. I usually practice 2 to 3 hours a day and take 3 days off from playing if I have a concert so my hands can rest. The one thing I do that many do not do is I talk to the audience and tell them what the next song is an who wrote it. The final few several minutes I ask the audience if they want to hear any certain songs.
Music is what feelings sound like.
Music is life, that why our hearts have beats.
