I am about to say something that I hope will not discourage you.
Here goes: if you had a talent for playing football and thought that professional footballers get paid a great deal of money, it would be a bit naive to think that, by taking up the sport, you could make a great deal of money.
The same applies in the writing world. Some professional writers make a great deal of money but it would be wrong to think that all writing is well paid. If you need some extra cash, you could earn more money working part time in a supermarket than you would be able to earn through writing.
Most of the authors here write for the love of writing.
