I believe forming an environmental personality is more important than forming a hereditary personality. Why I said this is because of the people around out can change your personality, and sometimes if you're with the wrong people, it can go wrong, with your personality too. You could have been a nice person at some time, you bur you hung out with the wrong people and now you're just very inconsiderate. Another reason on why I believe forming an environmental personality is more important because of the fact that maybe you could've been born with a parent who has a bad personality. You could try your best to be nicer by the choice of people you choose to be friends with.
