I want to encourage you, Crisi, and anyone else learning to play the piano. You feel doing a lot of laundry, according to your piano teacher, makes learning to play the piano difficult. There is probably some truth to that, but I think learning to play the piano is difficult, and it is important not to expect too much and be disappointed. Be happy with small gains. I play the piano for hours at a time, and I know that fatigue sets in, so don't be discouraged when it seems like a struggle to play after practicing a long time. On the other post I mentioned that I can't move my fingers quickly when they are cold. I have another problems. When I was 21 years old I had a horse accident. I hit the ground hard and severely broke my right wrist. It has never been the same since. I can't spread my fingers as wide nor do I have the agility with that right hand. So I will never be able to play like I could have if I had not broken my wrist. Also if I am digging with a shovel, chopping wood, using a hammer, or any other activity that requires strength from my right hand, after I work at jobs like that for a period of time, and then for a week after that when I play the piano my thumb and a couple of my fingers lose feeling until I have to quit playing. If I quit for even 5 or 10 minutes the feeling comes back and then I can play again for may 30 minutes until it happens again. If I do not do stressful work I can play non stop all day and into the night if I don't have anything else that I need to do.
The important thing is to keep working at it and not get discouraged because it will come, and your fingers in time will know where to go and they will do it quickly. A lot of times it does seem discouraging because often the progress is slow unless you are an unusual genius, and for most people the progress is slow. That is the reason I didn't learn years ago is that I got discouraged because I didn't learn it as fast as I thought I should. I still don't play as well as I want, but I am still working at it. Don't feel discouraged because other people can play well. Often they have had years and years of practice, and many times those people have a tendency to forget that they struggled at one time too. So try new things with the piano, and be happy with however you are able to play, and keep working at it, but don't stress, thinking that you will never get there because you will, and as times goes by, and you are still working at it, you will think back and be surprised at how well you are able to play.
