If we think the world is beautiful, it will look beautiful to us. 

If we think our task is easy, it will be easy to us. Although it's actually a hard, impossible task. 

Everything is from our mind. The way we set it or the way we think. All from our mind.

To have a strong mind, we must take care of our health. Don't overuse your energy, don't forget to eat, must have a " me time " and yup, have a quality sleep. If you feel exhausted, it will affect your mind. Pity your brain. It is tired like you. So take care ok.
