Part of personal development is also getting out of the comfort zone so we learn something new. This is not an easy task. So you need to be patient and persist. It doesn't matter what other people say. If you feel that your workplace is unpleasant, look for another job.
A trap lots of people fall into as part of personal development is to learn a little bit about many techniques, but not applying much. I do it myself. Personal development is very fascinating.
