I'm currently working in science, and ultimately interested in science and entrepreneurship. I don't have a PhD yet, and the financial situation in science and with startups makes me pretty nervous. Is it feasible for someone without a finance/business background to jump to an IB/PE job for a few years? I just want to feel more financially settled, before moving on with other things. I'm not quite 30-something, and if it helps at all my microecon professor in college apparently called my parents to get them to convince me to major in econ (I must have been the only one in the class who cared).
