Tip#1 Write, write, write whenever you are able. People learn by doing and if you want to know if it's for you. The only way to find out is try it. I spent years saying I'm going to write a book I want to be published. In order to gain the experience and knowledge it's best to go for it. I believe this can apply to any career choice. If you want to be a painter, paint. You want to be a photographer take pictures.
Tip#4 Do not fear the Thesaurus Get a calendar with a word of the day. Keep a thesaurus handy. Please, please, do not use the same words over and over. I drive myself nuts because I know which words are my favorites. I use find in my document find them all and then change them. Using different words challenges you to either describe differently or it avoids making your story sound repetitive. I have read published authors who have made this mistake. It takes away from the story. Make the effort to find another word for Red or book or magic. It makes a difference.
Tip#5 Participate in classes on writing, Attend conferences join a critique group. There is so much information out there. I've learned so much. Since I've begun taking classes and talking to other writers. Plus there's that bond that you form with other writers that you may not form with a non- writer exactly for that reason. Writing is art and who better to understand that, than another writer.
These are things that have helped me on my writing journey. I hope they have been some help to you.
May the words flow from your pen like they were meant to be there all along.
