Asserting our religion, belief or skepticism to ourselves and to others will ground us.
We should not understate ourselves or remain quiet when our tradition, belief or skepticism is disparaged, or ignored or misrepresented. Open mindedness is not passivity. We should voice our convictions.
At the same time, appreciating the belief of others will enhance our own faith in our own view of truth. Open mindedness is the opposite of arrogance.
