Consulting is a news business. You always have to stay updated, especially in your industries and practice areas. But also general news on business and technology is important. Since I have to drive a lot by car, I listen to the radio (e.g. BR24 or DLF Nova) and to the following podcasts, which are an awesome tool to educate yourself.
