Acceptance in terms of resignation and doing nothing about it - no. Why would anyone do that? That's ignoring it, not accepting it. Acceptance in terms of realising the problem is there and understanding that there are things you can do to alleviate it and improve, and things that you can't change - yes, this is realistic. Acceptance that there will be good days and bad days - yes, while recognising what's going on within yourself when things are good or bad. Acceptance that some days you're tired of it all and need a break from trying to control everything - yes, you need time to just be. Ultimately it's up to you to figure out how it manifests, what you can change and what you can't currently change, and employ services, therapists, friends, books, meditation, whatever helps. Self-acceptance is something many people struggle with, not just stutterers, and you are more than one trait. Learning about yourself, your favourable traits, your unfavourable traits, accepting, growing, changing, resolving inner conflicts - all these are part of life and apply to stuttering as much as anything else. Change can happen by itself, or you can direct it purposefully.
