If you could choose a business what would it be considering the times?

I would consider the trends, and choose a business that meets the needs of a GROWING market.
In the 50's vinyl records were a huge growing market, as was Kodak.
Today with the advent of digital music, the demand for vinyl records gets smaller everyday.
In the 70's PhotoHuts were a popular and lucrative franchise, ...however the advent of digital photography and desktop printing made photofinishing an ever shrinking market.
A McD's franchise is good... if you have a few million dollars lying around or can get financing for it, and have the luxury of waiting 5 yrs to even turn a profit....
Or you could choose a Network Marketing Business that provides you with none of the risk involved with a multi-million dollar traditional brick n' mortar business, with all of the upside potential.
Find a business that allows you to leverage your time, and your resources, but also allows you to leverage the time & resources of others.
In most businesses, you don't make any money at midnight. You're not even open, ...and if you are open for business, you are limited to walk-in traffic in your local vicinity. You may not be making money at midnight, ...but by golly, you are paying out money at midnight. As soon as that clock strikes midnight, you go into another day... which means paying out more overhead... more rent for another day, ...or more interest on the mortgage... but your business is closed.
You're paying out money 24 hrs a day... 7 days a week, ...but that's not how you're making it is it?
You will never win using that equation. To get ahead, your income needs to take on the same 24 hr a day... 7 day a week characteristic.
A Network Marketing business is GLOBAL in nature. It's midnight here on the East coast of North America, ...but it's noon in Japan & Korea. It's 3pm in the afternoon in Australia and 5am in the UK. The people over in the UK are about to wake up shortly and start their days. In a network marketing business, your income takes on the same 24 hr a day, 7 day a week characteristic without the risk, or overhead you contend with elsewhere. In a traditional business, an illness, or your inability to work for any period of time, can put you out of business. if you build your network mktg business properly, an illness, or a period of inactivity, doesn't stop your income. Infact, if you build it properly, your income will most likely actually accelerate. Build it right, and you couldn't stop the income even if you tried.
A network marketing business also allows yo the flexibility you won't find in a traditional business.. You spend years building a business, ...but natural disaster occurs, ...your employer or circumstances require you to re-locate, either temporarily or permanently... what do you do... leave all that hard work behind... or take it with you. With a network marketing business, ...you take it with you. Your vacations become tax writeoffs and business expenses, as do your clothes, and most expenses in your life.
Do you like Europe? Develop a network marketing business into European markets and legally write off your trips to Paris as a business expense. Travel the world and legally deduct these expenses. Fly to the Bahamas for the weekend and write it off. Do what you want, when you want, without any boss telling you when you can take a vacation and when you can't.
There's a reason successful men like Robert Kiyosaki and Donald Trump recommend network marketing.
There's also a reason why Warren Buffet is on a buying spree of network marketing companies. he describes them as
"The best money I ever spent".
