We recently we removed ourselves from social media despite societal pressure to be on it. We felt it was the best decision for a few reasons, one of which was to allocate time for school.

In a previous article, we wrote how one can go back to school for less than $300 to learn new skills and explore different career fields. Recently, I decided to follow this advice and take a CNC course to learn how things are manufactured.

CNC stands for computer numerical control which is a more advanced form of manufacturing. It’s basically a machine with numerous tools and a computer that controls how the tools are used to make a part.

One thing I learned right away is it’s not as simple as putting a piece of stock in the machine and hitting the power button. No, there’s math, precision measurement tools, programming and so much more. In addition to this, the tolerances we’re shooting for are less than half the thickness of a piece of paper. In sum, it’s been fascinating.

Unlike my classmates, I’m not getting a job in this field any time soon. The main reason I do this is to acquire skills because you never know when it may come in handy. I could lose my job or need a secondary income down the road. In this day and age, having backup in virtually every aspect of life is important – especially when it comes to taking care of a family.

Learning new things has its advantages. No matter what stage of life you’re in, it’s important to keep developing yourself so you don’t fall into a pattern of complacency.

Here’s another benefit of education: your house may burn and you could loose your possessions but no one can take the knowledge and skills you have.
