Self-sacrifice is admirable when family and dependents don't suffer from it. Realistically, most startups fail and it's negligent to place one's family on the line given the odds of failure.

Even for the sake of accumulating debt, it may not be wise (who knows when you'll need to take a loan for groceries, tuition, etc.)

I really hate how this attitude is so abundant, and rarely comes from somebody who knows what it is to live check-to-check, already be maxed out on loans, support a family, and still build something on the side.
