Mobility and networks
Mobility has always been part of the ideal of academia. On the way to a professorship, people will ask who accompanied you on your academic path and what names are associated with you. Therefore, do not spend your studies, doctorate and the entire postdoc or habilitation phase in the same place; your chances of a professorship later on will be significantly reduced. By changing location once or twice after your doctorate, you show your independence. But a stay abroad is no longer a must. International contacts are much more important. Use conferences to build up contacts at national and international level. Two new contacts per conference is a good benchmark. In addition to attending conferences, invite your colleagues to your colloquia. Invitations usually lead to return invitations.
