I have been in business many years, with varying degrees of success. It's tough. It's never easy for long. Always something to deal with. Something to watch. Always changing.
If you ever did stumble across a real successful venture... scale the hell out of it fast as someone somewhere will be watching and will do it bigger and faster soon.
It does make me laugh when someone claims they make $XXXX,00000 and are willing to let everyone in for a few $$$'s. Only seems to happen in the I.M. industry.
Every savvy business person knows you keep your cards close and hope for enough time to make a decent dime. Cash out at the top if you can. Sharing it... (if it even works) kills it fast.
My 2 cents. Good luck.
