you need luck sure, everybody needs luck, but some put themselves continously into positions where you can get lucky.
They also see a lucky donkey pass by and hop on (not sure if this is also a saying)
others let it pass, no matter how slow it gallops.
i also think people of average intelligence, who think they're smart, and the actual upper class of intelligence tend to think they're smarter then everyone.
-they fail because they start to big, think they can do it faster than most,
base their marketing on books and plans instead of trial and blow their whole budget on one campaign,
-they get the big shiny office and hire 10 people without profits because their business plan is so "smart"
-they tend to be snobby to customers, and inflexible to product or service changes
because their way is the smartest and the customer has to accept it
-they read forbes and enterpreneur and try to emulate big companies with healthy cash flow from their bank accounts
i could go on and on, i think smart people tend to over think things and make more dumb decisions
than your simple minded enterpreneur, who is flexible, cheap and puts the customer and his profits first.
you start small.
multiply a 1$ for a month each day and shit.
