1: You gave them up, only you didn't know it.

2: You were mistaking generalities for specifics ("finance" for example is actually a very broad economic sector, 1 out of 4 employed people can be considered to be in finance in some capacity)

3: Likely guesses based on available information like age, sex, education, location etc and universalities..most people consider themselves kind with short tempers even if they are not, or passionate, or wanting to see things through, or trusting but cautious. This is how horoscopes work. "Libra's are stubborn but loving" .

4: Your own selection bias..you note the hits, forget the misses.
