The greatest sailors are not those who sail superbly on smooth seas, but those who sail superbly on stormy seas. This is simple to understand.
Many sailors will sail well on a calm sea. How many are brave enough to sail through a stormy sea? The one who does so becomes outstanding.
This goes same for life. Many people are able to carry their heads up when the going is smooth. How many can do so when the going is rough?
You cannot create an impact in this world if you sail only on the easy seas of life. You have to build your muscles to sail through the stormy seas and emerge victorious.
