Read them over and find the bits and pieces that are good in them and then develop them into stories that meld the writer you were then with the writer you are now.
Take them out. Dust them off. Clean them up (re-read, edit, re-write, re-slant - whatever they need to get into shape). Identify a few markets and begin sending them out.
Don't have any.
Don't be afraid to show it to someone else. That is the only way you will get feed-back. Sure, it may hurt your feelings, but better your feelings be hurt than to never grow as a write. Take any criticism as a plus and learn from it. You may have your work red-lined for a while, but after a time those edits will be fewer and fewer.
Rehash and reuse.
Take another look, who knows you may have that next sucessful novel just waiting to be discovered.
CONSISTENCY IN WRITING.
Start by showing your friends. Then try a creative writing site or writing group to join and exchange ideas and critique.
If you have friends that read all the time, ask them to read what you wrote and give you their honest opinion about its marketability.
Reread them and see if there is anything in there that you can use in conjunction with something current. I have a lot of old travel articles, and revisiting areas, I can compare those notes with new ones. I have some stories that could be considered timeless, like the message in the bottle I dropped on a sail trip and was found a year and a half later.
I have bookcases of old notes and I reread them often for new ideas or new spins on old ideas.
I would recommend going back through them yourself and revising or editing them. From that, change what you think is right or don't change anything at all. But, re-reading pieces of work brings about such newfound knowledge it's incredible. You would be very surprised and I believe you would soon realize that writing is an art. And in art, there is no discrimination, there's just abstract and "hip."
Read them. If they don't interest you anymore, it probably isn't worth your time to hold onto them. If they still have a special place in your heart, show them to everyone. Show them to the people you think won't like them first, and finally to your closest family and friends that you know will love them. You might be surprised by the feedback you get. The only way to be a famous writer is to have people read your written work.
Keep it that way.
Really open your eyes and see them yourself first!!
First you must tell your friends and family about it. A little pep talk and inspiration from them will help boost your confidence up. Then, little by little you must start blogging to share it to the world.
