You need to know something...
Charm only works for the duration of brief exchanges with people, after that you should know and offer something of value in anything you are working on or talking about. This is especially true, in this new economic environment, at work. Pure knowledge alone is no longer enough if you are to be of real value, no matter what you do, in any organization. Doing the minimum required or going by the book is not working either, for you or any employer, whether you or they realize it or not.
It's up to us to make work more interesting and become more valuable in the job we're in or for the one we want. Others can't do that for us and neither can the amount, large or small, that we're paid. These days we need to know more than just our field of expertise, whether it's bending steel or programming bits or interacting with the public or managing people. We also need to make good decisions with our knowledge when we apply it and add value to the people we work with by quality interactions with them. That quality enriches everyone. Knowing the mechanics of what we do, whether it's machining a part, answering calls, guiding tours or directing the work of others, is only the ground level of what we do.
If you're doing something, even if it isn't your ideal situation, it always benefits you to make it worthwhile by going the extra step and adding quality. Otherwise minutes and hours are pure drudgery and you gain nothing and lose a lot. If you put a little creative thought into even the most rote task, doing more than following the policies and procedures to the letter, overcomes just being a piece part in the business. Even if it's not immediately apparent and only a small amount, you learn something by making it more challenging, adding to the job, totaling up to making your unique addition more valuable to yourself and who you work with.
It also keeps every day interesting. If you invest in what you're doing, it is returned to you in positive reactions by co-workers, a reciprocal beneficial reward.
