"I want to write."
There is not sentence that authors here more than that one, though it's followed closely by a a large number of other sentences.
Though I'm only nineteen years old, I've heard people say that to me over the years. I was the only person in my class that had actually finished a novel length work, thought I was probably one of five that actually wrote.
Just about every time someone learned that I wrote, they said, "I'd love to write, but I just couldn't do it."
I always heard someone that ranged from "I just don't have the patience." to "I just don't have the time."
Now, I shake my head when I hear someone say that. If someone really wanted to write, then they would.
It takes about 15 minutes for the average person to type 250 words. If you write for 15 minutes per day, you can write over 90,000 words in a year. Perhaps you can see why I shake me head now.
Regarding patience: well, I just don't understand that part. I'm incredibly impatience, but I love writing.
Perhaps some people just need to learn a little patience.
Now, I'll bring this to a conclusion.
If you want to write, then write. Don't let any excuses get in the way.
