I saw this this morning and it got to me.
These are five batteries. Only one of them is charged. They look alike in geometry and aesthetic view. Same design, different relevance...
When you are not charged , you lose your relevance.
This means a lot. In a world where technology is the happening thing, knowledge is dynamic and can be improved upon in split seconds, what you value as important today might not be so relevant tomorrow. Keep building yourself. Keep upgrading.
