When I was a young man, being in a different from everyone around me. I knew i have to try harder than everyone else. Being handicapped in many ways, I must have a better GPA and 10 time better interview skills than anyone else before I would have a job offer. This propelled me to work hard, since then I have never needed to find a job. Jobs will seek me; and i named my own salary.
When I was starting out, after being on the job for 2 weeks or so, I often set up an appointment to sit down with my boss to discuss his expectation and my performance. I made sure he was happy with me. Now i mentor all my employees and my children this way.
Don't look at it as a setback, look at it as a lesson for bigger things in life. Don't sweat the little thing, focus on the objective - Sail
