Brad - I'll tell you what it takes to diversify and its all about finding the right horse to ride. Get an executive from Dardin or Outback or some other huge franchise. These guys can be found, they're tired of what they've been doing and aspire for a new challenge (hint, ya know like we're discussing in this thread). Offer them sweat equity ownership in a franchise casual dining restaurant group and pay them well. From there, you just manage that person and as long as you made the right choice, its home free
The President of my food group sat on the board for Little Ceasars and was an executive at Paragon. He loves his job more than anything now, takes ownership in what he does, and has brought some the most talented people from his other organisations to build what we have today (and continue to build multiple restaurant locations every year).
I also agree with Mike - you'll get agressive again. It happens. I have a good idea when that might happen too. Assuming you are dumping a lot of cash into your 'nest egg' month to month, once you hit that 'magical' mark and you are truly ready to risk capital again, you'll go bananas
Success is PURELY a state of mind and once you've achieved it once that means you were cut from that fabric and it can happen again!
