Juggling a career and a family is a challenge for anyone, and even more so (in general) for women. Probably the most important advice to any woman interested in a career is to pick your life partner with care. Having a supportive partner is key to trying to manage the constraints of these two demanding roles.

Online education, then, can serve two goals. For students lucky enough to have access to great teachers, blended learning can mean even better outcomes at the same or lower cost.

As a society, we can and should invest more money in education.
