Dropping a Good Thing

I read  a story about a man who decided to sell chicken in bulk. It was a huge success.  The problem was that he didn’t think this was a sustainable model – despite the profits.  Therefore, he dropped the idea and went to pursue other things.  New ventures and jobs didn’t work out for him and he lost money. At the point where he was broke, her revisited the chicken business idea again. 

He went back to basics.The business model took off again. He incorporated new technology such as logging and trends. He reestablished himself and is doing well.

What are the things you have done and you dismissed because you didn’t think it was a long-term option?
