I work in an office environment that requires me to present quite frequently. As there are good days and bad days for stutterers like us, i generally preferred to influence the presentation slot to be towards the later half of the weekday (wed, thurs and fri) whereby i have already warm up alot and the chances of good day is higher. Occasionally, i still stutter quite abit during presentations. I don’t think my professional development is affected significantly. But i can imagine if i am more fluent with presentations, i might be able to climb the ladder faster
