In the repair room:
If I cut my finger, I’ll just glue it with a patch instead of calling an ambulance.
If I am heavily, before arterial bleeding, I will cut my arm - I will apply a burn and then call an ambulance.
If I have appendicitis, I will go to the doctor instead of doing the operation myself.
As well as repair. The burning lamp and the flowing crane I change myself. But to tint walls, to turn off electricity, to put tiles in the bathroom and parquet on the floor - I will hire specially trained people. Because it will eventually cost cheaper than doing it yourself (taking into account the time spent, the purchased tool, the dull materials and the subsequent removal of various cracks).
