Remove your stutter from the situation; without it, what do you want to do (not for the rest of your life, just for the next 2-3 years)? Go for that thing, make mistakes, try something new, make more mistakes, try other things, and eventually, you'll be enjoying life, and your stammer won't be a huge factor in who you are or how you live your life. Maybe those experiences will give you the confidence to run your dad's business. It doesn't seem that way now, but things will change, and you'll change. The point is, there isn't a typecast career path for people with stammers. We're everywhere (presidents, doctors, warehouse workers, accountants, bank tellers, cashiers, overnight grocery stockers, UPS delivery drivers, CEOs, entrepreneurs, software developers, onlyfans models, podcasters, musicians, real estate agents, actors, etc.) Choose your career path based on what you're good at and what you think you're comfortable with (after trying it out). I hope this helps. No matter what you do, please don't limit yourself because of your flaws. Live your life to the fullest despite them. Best of luck to you. You got this!
