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.<p>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.<p>What do you think about it?
