OK what's with u people today? Asking for life advice and opening delicate and intricate topics, has the summer boredom begun already? 
I understand what the guy is trying to say. I also understand that every person that considers this issue is likely to see it in their own way and understand it completely differently. I have to say that I have immense respect for people who have had the same job for 15yrs+ and have become an invaluable part of their company's work process. Achieving this carries a lot of respect in my book. On the other hand, consider the fact, that a young person in (most) developed countries has a very tough road ahead.
Why? Well it all starts in the education system which is simply horrible. Very few young people come out of high school knowing exactly what they're good at and what they want to do. On to college/university/w.e. (if ur lucky and got the grades earlier) where most people tend to find out they still have very little idea of what they want to do and how they want to do that. By this time they're very often 22+ yrs old, facing an existential and personal crisis, when they in fact should be starting their respective careers. They somehow pull through, get a job, realize they need a place to live or need to do some very extensive work on their home environment ergo need loads of money, which leads to loans that they obviously have to repay at a rate of 3:1 (they get 100k€, through the x amount of years they pay back a total of 300k€). What the hell kind of an outlook is that?
Now that's the most simple equation, if u factor in unexpected/unplanned children, failure to distinguish themselves before college and failing to get there, illness, serious injury, inability/inopportunity to get a job, insert various other problems here...., how attractive or even safe is the "standard" life style anyway? And what happens when u have so many loans or a big mortgage and u lose ur job? Yeah one can argue these things can never be predicted in someone's life, but aren't there enough worrying stories out there that they should at least warrant a serious consideration of this model of life?
That's why I decided to go for poker. I'd rather gamble with my life now for a few years then later when I might become unfit for work or who-knows-what-kind-of-disaster might strike. I chose to take my future solely into my own hands and to be completely self-reliant. That is what poker has become to me and that is why I'm more and more motivated to improve.
It is EXTREMELY difficult to get to a point where one can live off poker alone. It will take a lot of work and a lot of effort to get to that point. I'm lucky enough to be there and still manage to see a way to improve my fortunes, I doubt I'd achieve the kind of prospects if I had dragged my ass through college and have had a job for the past two years or so. Yeah I gambled but I don't gamble anymore today. For a while now all I do is improve and give all I can to improve even more. That's why I understand what this guy was trying to say and that's why I think it's worth to consider other paths through life.
