Here are five of my favorite quotes that always get me motivated and keep me going in the right direction:

“Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful”.
-Albert Schweitzer

“But there is suffering in life, and there are defeats. No one can avoid them. But it’s better to lose some of the battles in the struggles for your dreams than to be defeated without ever knowing what you’re fighting for”. – Paulo Coelho
