Opportunities and the career thing

I'm thinking of a change, however; change is scary when you've been employed with a company for over 10 years. Monday, I have an opportunity which I am not passing up. I am hopeful this new opportunity (interview) will lead to something wonderful that won't hold me back. Although my present company has presented me with opportunity to move around...gain knowledge and diversify my portfolio, I am just not happy with my current state. I blame poor judgement on my part but where there is poor judgement there is also knowledge gained. By Stepping outside my Sales/Account Manager role and in to a more logistical role, I have learned valuable information which allows me to expand on potential careers. I have also learned what it is like to work with impossible people, which is a valuable lesson. Anyway, if all goes well I hope to go in to full detail the company I am interviewing with. Wish me luck!
