Also, if you need to gamble your family's livelihood to find out if your spouse really loves you or not, why are you married? Similar sentiment for your friends. Being able to sympathize with the homeless sounds like a horrible return for sacrificing your livelihood. Dealing with backstabbing co-founders doesn't sound all that educational, just miserable. Fake people are a thing in all walks of life.
I don't come from the rosiest background in the world, I've had enough severe instability and drama forced upon me in the past to know there's nothing romantic about it. It should be avoided unless there's a tangible payoff, and certainly greater than a 10% chance of success.
My regular corporate job is currently giving me a stable platform upon which I can save, build up my household and consider launching a business on my own terms. It's also giving me valuable professional experience as I see how a large company ships product. I'm so glad I didn't go the startup route straight out of college, I've learned so much about business on the job that my engineering degree never remotely touched. It's hardly my dream job but I don't dread my work, nor do I feel like a zombie.
In 10 years I'll likely have enough saved up to seriously consider my own business, and enough contacts/professional clout to go back to regular work if it fails. I'll also have 10 more years of business experience to draw on, likely from at least 2 more companies. Why do a startup now, or God forbid right when I graduated, when I have/had the fewest resources and the fewest advantages?
