We are all the same. Deep down, at the core of each and everyone of us, we all have the same needs. We may be different in our approach, but that does not make us all that "different." We all have the capacity to love and to hate, to be kind and to be destructive, to be hurtful and to be caring.
Some people have so much battling in their mind, they may temporarily lose their way (or lose themselves). It could very well be you, or me. So before we judge others who have done "wrong" or did things we do not agree with, perhaps we should have some compassion and be thankful that life hasn't yet provoked us enough to show our own dark colors.
Even if you haven't yet been pushed to completely unleash your distasteful side, it doesn’t mean that given the "right" circumstances, you wouldn't become "that person" you dislike. So as it stands, you would be wiser to have compassion, understanding, and deep acceptance that life is challenging for each of us... and that you and I are equal — no matter what our exterior may show.
Deep down we are no different. Whatever it is that we are doing, we are doing it because we all want to be happy, we all want to be safe, and we all want to be loved. No matter how you look at it, you really only have one ultimate goal; and that is, fulfillment. Whatever you're doing, you're doing it because you want to feel fulfilled in some way.
Only YOU know what truly fulfills you. So choose the things (attitude, people, places, events, materials) that can bring more fulfillment to your life, and pay less attention to the things that take you away from it. Try to keep it simple. There's no reason to make things complicated.
Don't take life so seriously to a point where you forget to be "child-like" — to be young at heart. Remember, you have an inner child that lives deep within you who needs nurturing and attention. Let that inner child out to play often. Don't lock them up and shut them down. It's okay to cry, be angry, get frustrated and feel sad. A child would not hide these feelings for they are authentic... and so it is that you, too, are authentic when you express your true emotions.
Don't lose that inner child within who's filled with love, wonder and compassion. Don't confine to logic all the time. Be courageous and use your imagination. Sure, logic can get you from one place to the next, but imagination will take you everywhere!
Use this world as a discovery center. Explore everything as a child would. Get curious, wonder, inquire, try new things, mess around with new ways of doing things, toy with ideas, play with nature, venture out of your comfort zone. Don't take yourself so seriously... when something goes "wrong," instead of saying "Oh, no!" learn to say "Oh, well..."
