You can never be an artist if your work comes without effort - Amy Tan

I was writing for businesses. I think my mother was a little skeptical in the beginning, but fortunately, as a free-lance writer I was successful almost immediately. And so she was very proud, because she measured success in terms of money, which is what I started to do as well. My goal then, became to increase the amount of money that I made each month. Not simply each year, but each month — I mean, talk about pressure — to have more billable hours each month. So that by the end of my third year of being a free-lance writer, I was billing 90 hours a week. I had no time to sleep. I had no life. People said I was crazy, that I was a workaholic. And I couldn't understand how it was that I had these wonderful clients, and I was making all this money, and I wasn't happy and I didn't feel successful. That's when I started to write fiction.

too much happiness always overflowed into tears of sorrow.

"...I owed her a debt of gratitude. More than gratitude, much more.
I could finally see what had always been there. She had been more than an attendant, more than a friend, more than a sister. She had been a mother to me. She had worried, sought to protect me from danger, guided me toward the best. She had looked out for my future, assessed the worthiness of everyone to be in my life. And in that way, she had taken me as her purpose in life, the one who gave her meaning. I had a constant love all along. And in recognizing that, I felt moved to tears.
"How could you step out of my life?" I told her. "if you do don't join me, I will be lost. No one would worry about me as much as you. No one knows me better, knows my past and what this new life means. I should have told you a long time ago." I became teary-eyed. She kept her lips sealed, but her jaw was trembling. "You are the only loyal person in my life, the only one I can trust."
Tears fell from her eyes. "Now you know. I was always the only one."
"We love each other," I said with a light laugh. "In spite of all the trouble I've given you, you stayed with me. So it must be that you loved me like a mother.
