The reason why I'm actually going to change my job is that it's nearly impossible to find any library job at a bike-commutable distance.
There are plenty libraries in the town where I live, but somehow there aren't many vacancies.
The jobs that ARE available are always at least a 30mins train ride a way (and another 20 or 30mins bike ride to get to one of the 2 train stations )
At the moment I'm doing a course in bookkeeping as these jobs are available in every single town and every single company. 15K in winter and 25K in summer seemed perfect..
However, I've discovered that I love my own field too much and hence will become an indexer after having finished a course on indexing. That will mean that i'll work from my own home, but as I'm a member of a gym at 13K distance I am cycling there 3 times/week.
