Google says 18.4% of businesses in the U.S. fail within the first year. After five years, 49.7% fail and after 10 years, 65.5% of fail.
I don't like my odds.
It is a risk no doubt and that is why "owners" get paid way more than the common worker. It is your ass on the line. You could become wealthy or you could lose everything...work like crazy for three years only to see those thousands of hours flushed down the toilet because the government decides you forgot to cross a T or dot an I on some obscure requirement you didn't even know existed.
Or the government telling you that you have to close your business while others get to remain open during COVID.
No matter if someone owns a big business or a small one (which is how most big businesses start), it is your baby. You made sacrifices of yourself to feed it, clothe it, give it medical care and change its poopie diapers. You got up at all hours of the night because it was crying and you had to figure out what was wrong. You have been barfed on, peed on and functioned many a day on an hour of sleep and still you love it because it is a part of you.
If you go into business for yourself only with the purpose to make money, it will probably fail. It takes a very special person to start a business in your garage that becomes a global success.
It isn't all about the money. It is about making all of the hours you and your spouse spent sweating out whether or not you can make the mortgage payment this month, afford to pay for your kid to get braces or fix the machine that just broke down...it is about all of the baseball games and piano concerts you missed, all of the vacations you forewent, all of those hours of your life you spent trying to make something wonderful, where there once was nothing.
If you happen to "inherit" the business from your father, mother, grands...the pressure is even worse because it is not just your time and work that you are blowing, it is all of theirs as well.
People who have never been there, will never understand.
