Sometimes you face difficulties not because you're doing something wrong

God will not permit any troubles to come upon us, unless He has a specific plan by which great blessing can come out of the difficulty. - Peter Marshall
Your success and happiness lies in you. Resolve to keep happy, and your joy and you shall form an invincible host against difficulties. - Helen Keller
What is the difference between an obstacle and an opportunity? Our attitude toward it. Every opportunity has a difficulty, and every difficulty has an opportunity. - J. Sidlow Baxter
