Accepted an offer after 5 months after 6 years as a customer-service rep

After 5 months I accepted a job as a customer-service rep. I do not usually post, so bear with me. I am relieved and a bit nervous. What helped you in the first month?

Congratulations! Take notes on names and processes in your first week. It helped me settle in.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
