Caught between my brother's expectations and my own career path. What's your take?

My bro is pushing me hard to leave my tech job and help with our family's struggling store. He says it's on me to step up and keep things going for our parents. I see his point because the store is their life's work, and it would hurt to see it close. But I've spent years building my skills in software, and I finally landed a role I really enjoy with good pay. If I bail now, I might mess up my own future and regret it later. It feels like picking between letting my family down or giving up on my own goals. How have you all handled similar pushes from relatives about your work?
