Clear all obstacles in life

Life is full of obstacles. In the family, in the working places, we bound to face a lot of obstacles.
Many people will feel down or worries when obstacles come. If we can not clear these obstacles, we will feel depressed and find that life is miserable.
How to clear all these obstacles, yes, we can do it.
Firstly, we must have the right mindset in the first place. What are the right mindset? My thinking is as follow for your reference.
1. Do not hurt anybody. Why? because of not hurting any human things, we can feel peaceful in our heart. If we can extend the love to non-human being like animals willingly, we will be blessed beyond our imagination.
2. Tolerance-when we hear somebody talking bad about us, take it easy.
3.............many more.
What is your view?
