My dad was an avid reader when he was a kid. I remember him telling me about his regular trips to his public library, bringing home stacks of books.

He had a goal of reading all the books in the library. Maybe the world.

Then one day he realized: People were writing new books faster than he could read them. This meant he would never be able to read all the books.

From them on, he was much more selective about which books he read.

People are also building new languages and frameworks faster than anyone can learn them all. There will be always be more companies hiring than you can ever work for. Customers will always want new features faster than we can build them.

It’s important to learn to be selective.
