Risk
Accept a certain level of risk. Get information about the risk. Don’t try to get all information on the risk (it’s probbaly not achievable and leads to analysis paralysis).
Only get insurance for things whose loss would ruin you. This probably only leaves:
- personal liability insurance (Haftpflicht)
- disability insurance (Berufsunfähigkeit)
- fire / natural catastrophe insurance, only if you own a house or flat
