Haven't read the entire thread but my take is if you have to ask, don't do it. If you really wanted to and it was in your blood, you would have gone ahead no matter what anyone says here. Look, there is a reason why there is such a thing as a job and a career path and why most people do them even if they hate it. Job security and the ability to live a stable life is not without it's merits. Also, the longer you are out of a job, the harder it is to get gainful employment again, especially if you were simply trading from home. Your resume will simply have a big black hole.
There are tons of people here on ET who will tell you to go pursue your dreams. Most of them are retirees who already have worked their ENTIRE life and have a pension pot or high school kiddies or college freshmen full of fantasy and idealism and think they are the next Steve Cohen. For every 1 Bill Gates or Michael Dell or Steve Jobs, there are 500 Gates/Dell/Jobs who are still living in their parent's basement with no financial ability to get married, start a family or even go out with their friends for a drink and do any normal things that people do.
I took that step to become a trader, forsaking the normal career path and it has cost me in even though I was born into a relatively privileged family. Yes, I make a decent living now but knowing what I know now if I had to do it all over again, I don't think I would. It took a tremendous amount of time and effort and in the process, bridges were burned, weekends gone, friendships were lost, relationships broken. As you grow older, you realize some things are much more important than money. In the search for the ideal life, in exchange be prepared to give up this life. That is a real and distinct possibility. But hey as I said, If you really really wanted to do it, you would disregard what I just said.
But if I had to raise kids day in and day out I would blow my brains out. I always thought I was a very patient person but it turns out I'm a fucking OCD psycho.
