I may have posted this before but here's my take on it.
I embrace anger. It's a tool that when channeled correctly is very powerful. To me, uncontrolled anger is a lump of coal. It's soft, black, leaves marks on anything it touches, can be crushed and basically isn't worth much. Nobody really wants to hold it in their hands. It's messy.
If you're able to bottle it up a little, let the pressure build, feel the heat inside of that anger, you'll slowly start transforming that lump of coal into a Diamond. It's hard, beautiful, doesn't crush, takes in light and allows us to see the colors, can cut when needed and in general, it's value is far superior to coal.
So yes, it's okay to embrace anger. Just see it for what it is and use it appropriately.
