Schooling or training?
Both of them.
Big breaks? Disappointments?
I lost my first studio, I lost a lot of money but that was 10 years ago, it's past, over.
I work in fashion, editorials and commercial campaigns, model books ... a simple career.
I have no real hints on how to make a living, you have to love photography and invest your life. Hard work plus love, a lethal combination.
