Stand Up For Something! Stand up for WHAT YOU BELIEVE IN! Don't back down when people try to push you down for your beliefs, even if they are contrary to the what everyone else thinks! Even if you are alone in your convictions, at least you can hold your head up high knowing that you didn't back down.
As I have grown into my adult years, and especially as I have been married, I have come to find my (more conservative) beliefs causing more friction with people in my life. It has been a learning experience, and I have learned to stick my ground, even when people are not so nice.
Now this is not to say one should be rude. We must always be respectful to others and their differences of opinion. And often we will come to an understanding of, "Let's agree to disagree".
We must also take care to not judge others that believe differently than we do. We must love others and see the good in them and accept them for them. This does not mean we must surround ourselves with those that we don't care for, but we must always respect them.
Prepare yourself so that you may give educated, well spoken responses to those that question you. Prepare to not let others hurt your feelings. Understand that often people can't see beyond their own way of thinking. Know that what you have to say is not necessarily to change their opinion, it is to inform, to educate, hence why being prepared and knowledgeable is key.
Always try and see where others are coming from, and let them know you understand what they are saying.
Never bully those that are different. Our differences are what make this world such a beautiful, intriguing place.
Have integrity, grace, humility, sincerity, love and respect...always.
