We almost all start out as writers, writing specifically for ourselves. Either in journals or short stories, we mainly just write for our own needs. I started a journal in junior high and kept on going, mainly to discuss with myself my own complaints and life problems. I thought talking to myself might help, and it did to some extent.
But just as I grew out of only talking to myself, and into counseling where an outside person might help by interacting with my feelings and ideas, so most writers eventually decide to share their thoughts and ideas with others. Most finally decide that they are not just writing for themselves. They feel the need to share with others. When in fact, that may be the reason they started writing in the first place.
I would like to encourage you to share who you are through your writing. Share what you value and what you have learned! Make the world a less lonely place by telling others of your internal life. There may be others who could learn and grow and feel a little less alone by reading what you have written today.
Remember, the only thing you can do is tell your story and perhaps do some good along the way. If you keep your ultimate purpose in mind, your path will be easier.
Tell your story in the only way YOU can!
