Too many people are quick to slam you with their "overpriced" knowledge base. They believe because they know it, nothing else should be seen as good enough.
The way things are and looking to be heading, we will be needing to know more than we already know. There is no instrument that can do everything.
Wisdom is profitable to direct and that means, a man should be smart enough to know when to stop and when he should move. Thinking there is not need to learn because we think we already know what is to come is the most stupid thing anyone can do
What is may not be right every time so also what you know. There are times when the tides will change for better or worse and when it will tilt a bit to accommodate for failures or wins.
Growing means we have to be ready to let go of some stuffs that will hold us back and then follow through top be at a place where our heads will be free to think.
