Knowledge is like bricks: We collect them so we can build something.
Some people collect bricks in a few areas and can build a bridge between two bodies of knowledge.
Some people collect a lot of bricks in a single area and can reach new heights.
Some people collect a random assortment of bricks, and just use them to build a protective shield to keep others out. They might occasionally hurl a brick at others to insult or attempt to impress them.
Think about the bricks you're collecting, and what you plan to build with them.
