One of the best pieces of career advice I have received was probably to "always cover your actions." Here meaning that you should always have a good reason and process for doing what you're doing. For example, before you are asking a question, make sure the answer isn't otherwise available. Everything you do on the job should have a defensible reason.

Learn your product …be professional at all times and Listen carefully to what they are saying so that you can answer them and not waste time!

Learn all you can and rely on information that you have learned for this job.

If you can think it you can do it
