Get a pair of slippers. When you go to sleep, place them neatly next to your bed. When you leave your apartment, place them neatly next to your door. Heaven forbid you step into your living room with your street shoes!
Value your Feierabend after work more than anything and don’t forget to celebrate it with your daily Feierabend-beer.
Get as many types of insurance as you can find, from explosion insurance, legal expense insurance to bike insurance and tap water insurance. Don’t stop before you spend half your income on insurance, most of which you are not even sure what exactly they cover.
