Don’t blind others with your bright light.
When people spend most or all of their lives in darkness, it is very overwhelming for them to meet a light bearer. It is like when we have been in a dark movie theater, and come out to a bright sunny day! If they meet someone who is overly enthusiastic, positive, and cheerful, they think that person is a fake and must be trying to sell them something or harm them in some way. Therefore they become defensive and mistrusting of you. Instead of benefiting from your light, they put up shields to protect themselves, and end up even in a darker place than they were before.
So be aware of this fact when meeting new people. Although you never want to dim your light, you might consider softening it just a bit, so it does not get in their eyes, and they give you a chance to show them you are a friend and there to help them grow and have a better life.
