How to judge

 Why we think he is not qualified to conduct this orchestra? Of course,the age is the basis of judging in many areas whether a person has the qualification particularly in the world of classic music because classic musicians need to be trained very strict and learn many knowledge of the music. 
   When Gustavo Dudamel took over the orchestra in 1999, he is only 18. Most of people have not enter the university at 18 but he has owned his orchestra. Many people includes me have doubt whether he can run the orchestra well. The fact is he makes this orchestra to be one of the most popular symphony orchestra in the world. In 2004 he got the first prize at the Mahler conductor competition. In these years he led his orchestra performed in many places in the world. The orchestra has got a very good reputation and he was also appointed of the music director of Los Angeles Philharmonic Orchestra in 2009. 
    I think we can not judge a person only by his age just like we can not judge a book by its cover, the professional standard is the most important basis. This is what I realized.
