Never throw away old texts. Store them all and keep the files and hard prints. Also store the printed papers or magazines where your articles are published till you are dead. Hire storage space if it is too much for your own house.
Nowadays it is possible to launch your own website and publish your old things online. You will get some readers anyhow everyday and this will make you feel good as a writer.
Real devoted writers of the future will forget about narrowminded publishers, as I predict, and they will publish anything on their own personalized website to reach out to the whole world. It is sad to see how stupid we use the high tech internet nowaday, because it is so sophisticated and we use only ten percent of it’s capacity. Within ten years the speed of the internet will increase with 1000 000 percent. When so much capacity is wasted then also investment money is destroyed. We must develop more advanced ways of publishing books on the internet and to provide a living with it for the poor, lonely, forgotten and depressed writers.
For me it is such a sad feeling when an innocent tree must die to print a book of me. I save trees by publishing my stuff on my own website and get thousands of readers every month.
