Mehak Hossain believes that one must continue dreaming and talks about trusting the journey and daring to dream even when things seem impossible. Life has a way of surprising us with small miracles — opportunities, moments, and people — that meet us halfway when we refuse to give up. Mehak talks about hope, patience, and the quiet magic that happens when we keep believing, even in our toughest seasons. A quiet thinker, an observant learner, and someone who once explained gravity with more clarity than most of us had in our own exams.
