When we go through hardships, we start doubting our capabilities and this is normal for a human being. In this kind of situation, someone says to us that you can handle this situation and become better with full faith and conviction. That person is like a diamond in your life. Always value that person who has believed in you when everyone around you has started saying that you can't do your work or you're not good enough.
In this kind of situation, someone holds your hands and say that no matter what happens you can achieve your goals and you are more than enough to achieve excellence in your field.
