I'mma go against the flow here and just share some insights i've learned over time as a fellow amateur writer.
Write what you love
and love what you write.
Write for yourself, don't write for others.
Dedicate more time into researching than you do writing, know the subjects you incorporate into your novels.
Reach out to people with knowledge and experience with the subjects incorporated into your novel.
Find someone fluent in the english language to edit your novel and bring it to the next level. (or whatever language you are writing in).
The best places for writing are often times the places where you're left with only your thoughts. (A cabin out in the woods, a quiet park without many pedestrians, a hammock out in the backyard. Regardless, it is a place with your mind as the only distraction, and its often times there that you'll get some great ideas for your novel). It's also for this reason that you should carry a small notepad and pen with you for sudden bouts of inspiration.
If you keep these things in mind as you write, you'll realize there is no magical formula for success. All there is, is passion. Don't worry about originality, there's no such thing in this day and age.
