Life is inherently risky. There is only one big risk you should avoid at all costs, and that is the risk of doing nothing.
Don't be afraid to take a risk and stand up for what you know is right. When you see a wrong done, speak out from your heart and push for what is right, just and fair. Make yourself heard and the world (and you) will be better for it.
A good man brings good things out of the good stored up in his heart, and an evil man brings evil things out of the evil stored up in his heart. For the mouth speaks what the heart is full of.
