Vitamin, Painkiller Or Drug?

Lately I'm recovering from the first failure as an entrepreneur. The positive side of my failure is that I'm more interested in how to initiate startup that can be successful. Recently I found some articles referring to an idea for a startup as a vitamin or painkiller. But from my point of view there startps that are like a drug. Applications that are so addictive that helps your success will greatly increase. There are some examples such as some games that were designed when people become addicted to them. I believe that some services are also addictive as facebook or twitter. What do you think about it?
