What’s the difference between `self` and `this`?

Why do we have both?

Can’t we just have one?

The fact is, people are different. I’m different. Even when we are in fact, same.

I’m a Catholic, a husband, a father, a son, a brother and so many different things to others. However, one thing remains the same, I write code. This is where all those things come together.

Something new, but not really.
