I have read some words from one of my friends , I think it is meaningful, then I translated it in English.

You should be thankful to the person who forces you to overcome yourself, He is the mentor in your life and because of that you might change and transform. Growth is when you do what you have not done before, change is when you do something you were not willing to do and overcoming yourself is when you do something that you did not dare to do. It is clear that you believe in the ability of God when you seek God's assistance and it is clear God has confidence in your abilities when he did not assist you.
