## Maths is Useless!

It gives me a headache every time I think about it. I took a horrible module called Mathematical Economics under Visiting Professor John Quah last semester. I was questioning the usefulness of this module throughout the whole semester until the final exam. Then I had an epiphany on applying it in life.

I bet many of you have done that throughout your schooling years and have asked the same question, “how will any of this help me at all?” Let me give you a hand in answering that today.

I am sure many of you are familiar with the concept of FUNCTIONS. Leonhard Euler introduced this concept in the 1700s. Basically, you have an input (x) and an output (f(x)). A function is a relationship between them.

In many ways, functions are all around us. Firms have a production function, a profit function. In a country, we have consumption function…yada yada…Scaling it down, we can think in terms of functions too.

Apply this concept throughout your whole life. Be it relationships with others, work, etc, it is possible to think of them in terms of functions. For example, grades. You have many variables that can affect your grades. Hours spent studying, hours spent on leisure…you name it.

However, there is one variable that you can control which can bring you the most results.

Heard of the 80/20 rule? It states that 80% of your results can be determined by 20% of your efforts. Gary Keller in his book, The ONE Thing, narrowed the 20% into just ONE thing. This one thing(variable) can bring you extreme results. To find that ONE thing, you just gotta ask yourself some questions.

If you still do not know what’s that ONE thing, experiment around! Find which variable will bring you success. Do not falter even if you “fail”, they are experiments to guide you to the ONE thing. Keep working at it, and do not be afraid to change things up. After all,

“Insanity is doing the same thing over and over again and expecting different results” – Albert Einstein

Now, who ever said maths is useless?
