Hello !
Just try it yourself. No reason to ask here. You will receive tons of arguments why you can't success in that. So psychologically it won't help you and can stop you, because you can start doubt in what you think can work.
You think something works, stick to it, to that 1 thing, don't jump around other "technics", "strategies", "tools", try to do that 1 thing best you can.
Do you have a chance ? Of course, why not, there are such stories. Is it very probable ? Not really, but you shouldn't focus on that part.
You wrote about forum of professionals. I guarantee you that more then 50% ppl here didn't make it and they still can't, so you will hear why you can't too. There is also group of those who made it and scold you, because they now how hard it was and just saw too many failures. But let's give the man a chance.
