Doing a bioinformatics Masters degree. Had 15 years molecular biology wet lab experience and was getting very bored with the repetitiveness of it. Did the degree, learnt to code. Now earn more money, much safer in a highly competitive job market, and most importantly really enjoy what I'm doing.

Without taking the time to do the degree, none of it would have happened. Had 2 kids whilst working and studying - come to think of it, a supportive wife was by far the best decision career wise.
