The below 3 simple rules are not only true for life in general but also for writers who want to get ahead.
1. Know your goals and go after them. Set aside time to work on your writing. Promote your writing. If you want to be a writer, be one.
2. Don't be afraid to ask. ASK other writers for help and advice. ASK people to support your writing. You might be surprised at how many say yes.
3. Step out of your comfort zone, both with your writing and how you promote it. Try new genres and experiment with your writing. Do a book signing or speak at a conference. You might just find that you're the only one holding you back.
