I think in some cases it is neccesary. Depends on the industry or chosen field. In my case it doesnt really apply. I had experience in the IT industry but in a completely different field then my chosen business. So I had no direct experience when starting it. Innovative ideas can apply to existing product solutions. I guess it just depends on your knowledge and ability to adapt and take change. Everyone is different. To most I would make the same suggestion. There are the few that will succeed no matter what though.
Enjoy Life,

When I stand before God at the end of my life, I would hope that I would not have a single bit of talent left, and could say, "I used everything you gave me."
