Earth Snake Relationship and Career

Is it true that Earth Snakes will go through being crossed in love? Will they get cheated on for lack of romance? Why do male Earth Snake people have bad luck with a wife, or girlfriend? 

Also, why Earth Snakes are not able to study or concentrate? Are they stupid? How can they master this?

Can an Earth Snake be a surgeon? Is it natural?

Can Earth Snakes get revenge easily? How dangerous are they?

Thank you
