My father used to grow oranges and grapefruit in his yard at his old house in Florida. He used to go out every day and tend to them, checking the soil, paying attention to the moisture, reacting to drastic changes in temperature, etc. Those trees had it good!
As you can imagine, the fruit coming from those branches was some of the tastiest fruit I’d ever experienced. Juicy and zesty, I would close my eyes in ecstasy as my tongue danced in reaction to the flavor.
Writing is like that too. I wrote and rewrote my novel, Deadly Gratitude, over a period of eight years. I read, re-read, and re-worked the pages over and over and over again. I solicited suggestions from those with knowledge. Then I re-read it and re-worked it again.
I know a number of writers and one complaint I hear is the fact that they are tired of their current work and they don’t want to keep slaving away over it. In some cases, maybe quitting is the way to go. Perhaps what was important to be learned was learned and can be incorporated into the next work.
But in some cases, it’s important to keep the effort going. At times, it can be a bit of a grind. But your work improves incrementally each day. Perseverance is merely simple math. The sum of the repeated incremental improvements equals monumental achievement.
So, stay with it. Believe in your work. And most of all, believe in yourself.
