What does it mean to be a professional?
Do you have a specific job to do?
Can your success be measured? (Even if it is only you who are doing the measuring.)
Are you able to be better at your job today than you were yesterday? Do you try to be better?
Do you keep working even when the boss isn’t looking?

And Most Importantly:

Do you work to make your customers, coworkers, supervisors, and company succeed?

If you can answer yes, then you are a professional.
