One writes what one lives, even if not in a literal way. Someone who has gone through an unhappy love tends to describe unhappy loves, even if they have nothing to do with their own.
In a novel there's not much autobiography. There are characters in transit. Naturally, I can project something of my experiences onto the characters, but they have their own autonomy, a personality that is often a mystery to me.
Success is something you should never take into consideration: if you follow it it'll elude you. It's important to really love your work as a writer, to read loads to the point where you can recognise blindfolded, hearing them read, the writers of yesterday and today. It's important to write every day, for hours. To have faith in your imagination and let it wander.
Adults don't know how to respect and really love their young ones. Often love is confused with possession. You say "this is my" about your child, without taking into account that you're dealing with a real person with his/her own personality, rights, and autonomy, even when very young.
For my whole life I have dedicated myself to those who have been subjected to injustice. I've conducted investigations and written in newspapers about the homeless, the incarcerated, the sick excluded from care, about child labor, child exploitation, etc.
I try to cultivate friendships, because they are great assets. And I tend to make them last over time. Nevertheless sometimes they end mysteriously and you don't really know for what reason. Just like loves.=
Writing is a solitary activity, it requires isolation and silence.
Besides, everywhere, life is getting longer, marriages fall apart, divorce is a reality that happens even where the law doesn't sanction it. It remains the tradition that women are trusted to take care of the children.
Don't wait for success, but for the respect and interest of those who read you. At the start it could be a classmate, someone who shares your interests. Before sending off the manuscript for a novel to a publishing house, it would be a good idea to try writing short stories, and publishing them in a local magazine.
