"You weren't an accident.You weren't mass produced.You aren't an assembly line product. You were deliberately planned, specifically gifted and lovingly positioned on Earth by the Master Craftsman."
Therefore, we have to make our lives count. Since we can only control three things in our life -- our thoughts, our visions and our actions -- we have to use them positively by continuously believing in our self, our dreams, our hopes even if no one else does.
It's a matter of attitude and we always have a choice. We can choose to believe or not to believe. Since it's the latter one that brings in more blessings and great things, why choose otherwise, right? Don't waste your life saying or believing you can't. Stop minding what others think of you. It's none of your business anyway so just go ahead and focus on the things that you can and want to do.
