Life is dynamic, and nobody has control over those changes. Sometimes things go well, and sometimes they do not. Things will not always go as we want, and it is during those times that things are not going exactly the way we want that growth happens.
When everything is going well, you can be happy and have large visions. But when things are taking a downturn, being able to keep your head high, stay focused, and motivated are the things that make growth happen.
This is the point at which you evaluate yourself. That problem that you are going through are you going through it or growing through it? Access the situation and learn from it.
