When i was at school i never worked over the summer so i finally started my Apprenticeship in August 2001. I didn't know what job i would want to go for so i took something that sounded not to bad to me.
"Fachkraft für Lagerwirtschaft" -> "Specialist for Warehouse Management" (Google Translation)
This year in August i am hopefully becoming a Master in this and can call myself "Meister" then:
"Meister für Lagerwirtschaft" -> "Master of Warehouse Management"
So since i started learning my job and working in it i never switched professions and i still like my job.
So almost 10 years done only 30 more to go until i can retire
