Your profession absolutely has everything to do with your stability of life

What I said was that there is more to stability of life than having a normal job. If you don't know how to live by your means or are prone to making poor decisions, you can easily destroy your life no matter what kind of job you have. And until smash tournaments become so rare M2k can't make money off of them, it is reasonable to expect that he can continue to make money off of them.

I'm honestly not even sure what you meant by these. Having poor interpersonal relationships is not at all dependent on your profession and is simply a personal issue. Likewise, amassing large debt or suffering a critical accident are difficult situations, but I fail to see how that relates to why playing video games as a profession is a viable opportunity (for most).

Because having a certain kind of job does not guarantee anything for all people, which is the only thing I'm saying. If you live by your means then of course most jobs will afford a decent life. But just look at how many athletes end up in bankruptcy after having made more money than some people will make in a lifetime.

A consistent job gives you a steady paycheck, and usually a pretty stable schedule. It gives you career growth opportunities and sometimes it even gives you additional workplace benefits, such as insurance for you and your family.

Now you're saying normal jobs give a steady paycheck, stable schedule, growth opportunities, and workplace benefits. Obviously video gaming doesn't fall into this definition of a normal job, but then neither do a lot of other "normal" jobs.
