Five quanlities

I think the five quanlities that a good inventor should have are working because that can make the inventor keep trying.
Then good inventor should be intelligent because inventor should think lots of ideas about the inventions.
Good inventor should be brave because when making some inventions there will have some dangerous and thhe inventor shoulld be brave.
Next good inventors should be patient because making inventions will defeat a lot and if the inventor hasn't any patient and he will not try it again and again.
Finally, good inventor should observe things carefully because before making invention there should have lots of observation and if them observe carelessly they should not have any good inventions.
