Does it matter which country I am in to pursue this dive?
The best thing about novel writing is that no matter where you are in the world, you can quite easily develop and write your novels.    As long as you have access to a laptop (or pen and paper), you will be able to practice your skills, improving every day.
The bottom line, the answer is no: it doesn't matter at all which country you are in. Wherever you are, you can start learning or improve your Novel Writing skills.
