What causes "overnight success" ?

Have you ever started a job or gone into a new profession without being trained? Did you go down to your local discount store and order a kit to be a lawyer, a doctor, or an engineer? Of course not - to enter those professions, you need specialized knowledge.

What about when you started a job? Did you just walk in off the street and tell them you knew all there was to know about the job and no training would be necessary? I don't think so. According to most Fortune 500 companies, it takes 6 months of being on the job before the company starts to make any money from an employee. Did you read that closely 6 months?
