The brick is heavy, and when you drop it, it hits the floor, and pieces chip off, but it’s still together.
The functions of a brick are limited; it can be used to build something, although without mortar, it would fall over.
Carrying it is heavy, and it weighs you down.
It needs more to become something useful; it needs mortar, it needs precision, it needs levelling, and other bricks.
And once altogether, it becomes something useful.
By itself, not so great, but when together, awesomeness.
Don’t be a brick, when you could work with a team and be awesome.
