Mozart had his up and his downs. Most of his success was during his childhood and the last few years of his life. During his mid-life he had alot of things go wrong, I know he tried for lead composer but was turned down several times. It wasn't until the Giovanni Opera until he finally made it. Also throughout the rest of the world he didn't have commercial success, the french and italians mostly. He made his career in Prague I believe. Like most genius of there art, he was not truely appreciated by the world until after his death.
