Writing is a way of life. A few years ago a study came up with the astounding statistic that the average man can't go fifteen seconds without thinking about sex. I don't know if that is true, but I do know that in my own life I can't go more than a few minutes without thinking of writing. It's a constant awareness, a way of life. However, you can increase the chances of your being successful at writing by making writing a way of life.
Writing is a mindset, a psychological view of life.
A spiderweb won't simply be a spider's dinner table but an essay possibility. If you really want to write, get rid of the excuses in your life that prevent you from writing. But you see, in life we do the things we really want to do. We make time for those things that are important to us. So don't let anything hold you back.
