Why Do I

Why do I write?
I wish I knew.
I write about me,
I write about you.
I will write about happy,
I will write, if I'm sad,
I will write when I'm good,
I won't write if I'm bad.
I write for you readers,
I will write directly to you,
For writing is joyful,
It matters not what I do,
As long as I write for many,
Not just a few.
