Your worldview is worth considering.  If you have a faith, for example, it might be beneficial for your mental health.  This study suggested that, “Religion appears to be one important way of having a sense of well-being.”

Of course, it can go the other way too.  If you’re gay, lesbian or trans and a part of a conservative religious group it will likely have a significantly negative impact on your mental health.

Temperament is another interesting one.  Some of you will be what we refer to as, “highly sensitive.”  This doesn’t mean you’re soft or weak or a lesser person, it just means that your default in life is to be exquisitely sensitive to the world and people around you.  It’s a rich and beautiful temperament type to have, but it also means that you tend to feel things like sadness more deeply than others.  You can read more about the highly sensitive person here (www.hsperson.com).
