There are those strong souls who keep their joy of writing and can still write about things they would rather not write. I do not know if I would have written anything if it were not for the joy of writing when I first put pen to paper in a meaningful way. I reckon that when someone experiences the joy of writing for the first time is how all other writing begins. At least, that is how I feel.
Unfortunately, joy may not last. When I first played cricket, there was the joy of cricket for the sake of cricket, but then comes performing which may produce pain if one isn’t performing well enough. It can be the same in writing. One’s joy may not last.
Yet pain in writing can be useful. The initial joy in writing is really baby-like and temporal, but there is a time for the pain of learning about what we need to improve on. We go to school. In doing our homework, pain comes at night, but once we master something, there is joy in the morning. One moves on from the initial, euphoric child-like joy of writing to the satisfaction of mastering something.
