I write embedded controls software for big yellow machines.

Then I come to robots and help write embedded controls software for smaller red and white machines.

Embedded controls software is fun!

My thoughts from doing this for two years:

What exactly is a STEM field look like on a day-to-day basis? Lots of problem solving. Real-time problem solving. The skills you learn through First, or in school, or at work, or in your free time, these are tools to help you problem solve. The most important tool in your bag is your desire to learn new things - this is what lets you add new tools to your problem-solving bag at will.

You'll probably start out solving problems directly related to specific issues with products. Some people like that and stick with it for their whole careers. Some folks move on to solve higher-level problems, like planning larger-scale projects, or finances, or people management. All of these, through the lens of "STEM", can be thought of as simply a problem to solve. A problem which can be solved by drawing on your knowledge and experiences (the tools in your bag). A problem which may push your boundaries, and force you to develop new skills.
