You introduce an input into a function to get an output.

If you want to change the output, you can either change the function or the input.

In life, what should we change?

The function or the input?

In life, neither is particularly certain.

Here I am. Here’s where I want to go. What do I need to do to get there?

This train of thought focuses on function.

But what if the more important element to change is the input.

Faulty input into any function will not lead to a strong outcome.
