This is really important. You have been learning new things from this job and have been applying them to what you already know.

Even though you feel the individuals you are working with know more than you do? What matters more is that you have the ability to not only learn from them, but you can be an encouraging presence to them as well. Senior strategist doesn't have to always have "all" the knowledge either, often what is more important is being able to recognize the positive contributions these workers you are mentoring are presenting to you and being a presence that validates, respects and encourages. It's OK if you are learning some things from these individuals and truth be told, that tends to happen a lot anyway when dealing with younger minds full of ideas and imaginations that are fresh in very much reflecting "that" particular generation. Remember how you saw things an old boss was not willing to see and how after you left that job what you had warned ended up happening? Well, that actually was an important lesson that you can utilize in this job where you are more willing to have an open mind with these other workers that you feel have more skills than you do.

So far you have had positive feedback, so go with that instead of feeling you have to approach your superiors with feelings that you are not qualified. Give yourself time to learn and adjust. Sometimes the most valuable asset golden_eye is a presence that fits good in the group environment that you have described as being a nice "friendly" environment. Actually, I think you really will benefit from this kind of environment.
