Focus on the things you have control over, and try not to focus so much on the things you have no control over. You have a stutter. Sure, you can go to speech therapy and learn techniques to help you speak more fluently, but until a major, front-page-headline neurological breakthrough occurs, you will always stutter. You can't change that. So what *can* you change? Well, you can start eating healthy and drinking more water every day, if you aren't already. If you're addicted to alcohol or nicotine, you can overcome that. If you don't exercise regularly, you can start. If you spend hours of each day mindlessly scrolling on your preferred social medium, you can start doing something productive, something that won't make you feel like you've wasted the day when you're lying in bed at night. I turn 30 next month, and what's in the above paragraph is the stuff I wish I had focused on when I was your age. But let's say you're already in good health and happy with most other aspects of your life: If you want help navigating life with a stutter, my advice is to live your life as if you *don't* stutter. You mentioned your dad's company. Do you want to take it over? If so, do it. If not, do whatever else it is you want to do, and whatever that thing is, don't let the fear of unavoidable speaking situations keep you from it. Avoiding speaking doesn't do anything but provide you a temporary relief and add to the regret you'll feel later in life.
