Its take courage to believe in something.
It takes courage to look people in the face and say I believe in this and I am going to pursue it, no matter the risks, the odds, the negativity of others.
I remember when I was a little kid, and I came home in tears. My Mum of course wanted to know what had happened. I told her my sob story about people, their negativity and meanness. And she said the weirdest thing. She said they are jealous, plain and simple. My tears subsided and my eyes opened wide like UFO's. "Jealous of WHAT? " I asked her, especially since we lived a very simple life in a small apartment. She very wisely said, even when you think you have nothing, you may still have more than the next person whether this is material possessions, a sunny disposition or a strength within. She told me to brush it off and continue to believe in myself no matters what others may say. You need to depend on You.
Yes support systems are great to have but sometimes these may fail and you need to be able to get up and get going, come what may.
You are brave, you are strong, you are courageous !
