improving modelling skills (desideratum)

[imagine]

Hello,

Anybody knows about good tutorials or books to improve modelling skills?

I know there're lot of tutorials in this forum and all around the web but I'm looking for a general tutorial about modelling

When modelling I always think it should be another easier way to resolve the model or I tend to use a lot of steps and after time I discover there's a command or a set of commads that do exactly what I've done more complicated

So I'm searching a book or series of tutorials to help me improve my skills or my modelling style, what tecniques are common use and what solutions are common adopted, a tutorial of best practices if you want ;-)
