Needing money is the #1 excuse for avoiding founding a business.
I have helped found two businesses. The first I put in all I had (~10k), and the second was founded a year later because the first was failing and I was essentially broke. The 3 co-founders who all had small children drew down mortgages to fund themselves. Being hungry for money, we started doing some irrelevant consulting to pay ourselves some money: which was about minimum wage for the first year (not enough to pay all bills). I lived in a derelict building with opiate addicts (not my scene, but it was my friend’s addiction). As founders we were fortunate that we couldn’t get VC funding, since now we still own all of the business. The business hasn’t turned into a unicorn, but has been mildly successful, and now the founders have a better financial story than most first employees (@1%).
YC provides living expenses while you validate your idea and get funding.
There is usually a way to succeed but you must have the right thought patterns. If you are the sort of person who finds excuses, you are far better off being an employee. The amount of money a good engineer in the US can earn is astonishing.
On average, being a founder is a financially stupid decision. Most VC funds fail, and VC has seniority for any business sale, so founders have a much higher risk than VC. The chance of a 20% payout is nowhere near enough to cover the risks of failing. Be an employee, take your 1%, value it at $0, and enjoy banking your low risk salary and avoid screwing your health and have a social life and look after your family.
Please, try to avoid selection bias where you see a founder win $200M but you ignore the other majority of founders who failed and ended up with $0 and a broken life.
