Our culture lionizes entrepreneurs who navigate daring switchbacks in their career. Steve Jobs was admired not just for Apple, but also his detour to found Pixar. Elon Musk is revered for helming Tesla AND SpaceX. But don't be distracted by other people's winding paths. I believe you should celebrate your single-mindedness, and stick to your own overarching idea — for as long as it holds your own fascination. In my experience, that could last your entire career.
