Some suggestions for you :
Be helpful. When you see a person without a smile, give him one of yours.
When I became proficient as a salesman I was invited to teach new hires.
When you catch a glimpse of your potential, that's when passion is born.
Expect the best. Prepare for the worst. Capitalize on what comes.
It's not where you start - it's where you finish that counts.
