Hello countrymath,
There is something I want to tell, excuse me if I use your post for this, buy I think it is not going to help me clear my mind, but also make us reflex in what is really important in a personal way.
This year I am going to take a propadaeutic admission exam in my country. The aim of the propadaeutic is to prepare the possible aspirants for the real admission exam which will be taken in around 3 years.
Yesterday, there was a vocacional presentation about the area, besides the areas for clavichord, organ, accordeon and musical education. The first three areas didn't have enough aspirants, (maximum 30 I think) and their presentations were quite tranquil and inspiring in order to enter.
Now here comes the main course: Piano and Musical Education.
When the topic for Piano came, many of us (around 1000 aspirants) raised our hands. The teacher made an elaborate presentation, pointing out that the jury will check many points (memorizing, notes, pedal, speed, rythym, following exactly the scores, posture, etc) and this year there will only be 27 who can get a place because piano is a very demanding area, both in study and work.
I became anxious, because there are many points which I haven't covered yet, and also because they mentioned that it will not only consist in playing, it will have also to cover many issues: social work, get many jobs, be updated in many topics, etc.

It was as if they were talking us as if we are going to start to take the major even though this will be in 3 years. (and maybe not all the 27 people who are going to be chosen will make it)
In other words, the teacher said many things that can discourage so you won't take the area if you are not going to take it "seriously" in the future.
The presentation of musical education was moreless the same, but it was more relaxed than
piano.
Now when I think of it, I started to think why I decided to enter to the exam: I decided to enter because I want to use is as something to encourage me to go on and improve in my musical abilities. Unfortunately I got accostumed since school to be evaluated with exams, numbers and letters and I am usually looking for approval of those whom I think they will know.
My aim of doing the exam is to know where should I improve.
Thinking that I must be perfect makes me anxious, impatient, depressive and makes me make more mistakes, so I think that I cannot become a professional (or maybe I can but in another school).
The issues arrive when I start to think seriously in the things and I forget that the most important thing is to improve, accept all the critics like water off a duck's back and don't forget to have fun.
