There is nothing worse than realizing you are an accessory.
It may not be a conscious thought on the part of others or something that they are even aware that they are doing (hopefully not, because otherwise there are worse issues involved). They may see it as a simple taking charge of the situation to make sure that things get done or even that if someone else will not lead (whatever their definition of that is), they will do so. But what ends up happening is that one ends up being an accessory.
What do I mean? The fact that your participation and acceptance are assumed. That you have no other opinion beyond that of what has been decided by others, that your will is simply that of the majority (or whoever is making the decisions), and that your lack of silence about the whole thing is really an indication of your acceptance of this fact, rather than any indication that you may silently not agree or simply would rather not create a situation in the first place. And then, once the action is completed or the task done, you are simply put back on the shelf or returned to your place, a piece of jewelry that has served its purpose, the tool that has helped to complete the task.
It leaves the person in question, the one who has been the accessory, feeling a little less enthused over time. One no longer has a role or purpose beyond that which is filled in the lives of those who need the accessory. Enthusiasm is only shown when one does the thing which the other person wants or feels is necessary and like a Pavlovian response, excitement and attention are paid - but try something which is not directly in plan or is even counter to it and one will find that the excitement and attention fade away faster than cherry blossoms in the wind. Appreciation often feels to be extended because of what one does, not because of who one is.
How does one handle this? Unfortunately, there seem to be no good options. If a superior is treating you this way, they generally view any reaction or complaint as simply being insubordinate or having authority issues - after all, the point of reports is to serve and take their suggestions seriously. If it is someone else, an equal or even a loved one, they either will not see the issue or consider any note of it as a sign that you are selfish or self absorbed, not a team player or concerned with the bigger picture. The options become either to put one's foot down and thereby create arguments and disagreements and hurt feelings or simple go along with the flow, side-stepping any unfortunate incidents and gently sighing inside.
There is one thing, one thing that the outside will never see though: every time the accessory is used as an accessory, a little piece of free will and responsiveness goes away, heading off to either an inner reservoir of resistance or to a place where things are different. Continued long enough, all that will remain is the vehicle which can be used, the accessory which decorates or fixes.
The will, the inner core, the engagement, will have gone elsewhere.
