The only right career is owning a small farm with sufficient output to provide for one's family. Everything else is supplemental.
Of course, if I choose to have kids, then this course would alter. I would have to shoulder the responsibility of being my kids' sole provider til they are able to fend for themselves. If I'm married and have taken the vow, then I would abide by my spouse til death do us part. I would also without a doubt, see my aged old parents whom did not managed to save for retirement well into their golden years.
All that above is only when I have made the conscious effort to start a family. Otherwise, providing for one's family cannot be the motivator for starting a firm and letting all else - things pertaining to my self-interests and ambitions take a back seat don't seem logical to me at all.
I know reality is crushing. I also know I have the power to think and to change things. I will not succumb.
Somewhere, there's someone that loves you enough to accept you for this. ;) Everyone needs family, even Bruce Wayne and Clark Kent.
Can we not whimsically redefine words that are already well-defined or at least explicitly state how you want to use it if you're going to make a generic statement with it else stick to it's common meaning.
Unfortunately (or maybe not), the world (and the organic chemistry that you are made of) is not a collection of rational entities. It is extremely hard to stay rational in that context. Good luck with trying to do that. (meant non-sarcastically)
In my experience, people are social creatures. We like to find a tribe, we like to help others, and we like social networks that stretch beyond a single partner and children.
Farming for yourself is a very inefficient way to live.
Not trying to convince you to change, each to his own, but just pointing out that you may be missing out on some good things in life.
That would suffice.
