Take it or leave it, that's all about life, so why not live happily?
We may not be able to change the world in the rest of our life, but we can change our sight. There's always something worth to fight for, not just about money, reputation, justice or something else like that.
Just take a break and look around yourself, it's beautiful doesn't it? Every tree, every flower, every stone, every grain of sand is a master piece.
Treasures every single day, everyone you met in your life. You may not have a second chance to meet them again.
